It's VERY explicitness can also support the possibility of Quickness being disrupted. Why? Because there is a need for naming 1 action casting time to ensure that you couldn't mistakenly assume that Quickened applied to the first part of that "OR" conjunctive, the AoO.
Now, that is really stretching. In "or" sentences, any of them are applicable. In the case we are talking about, the only portions of the sentence that is relative is:
"damage stemming from readied attack made in response to the spell being cast for spells with a casting time of 1 action"

I'll set aside the logic of consistancy arguement since it has a weak weighting at the level we are dealing at and, though I am sure I understand your point that there are places where you could say there is a possibility that there is no way to disrupt a Quickened spell by a simple readied damage dealing attack, I still feel overwhelmingly secure that you have not provided any entries, such that I have, that are explicit proof positive.
We have 4 bits of information here:
1) That they were explicit about distractions for spells with a casting time of one round or more and for spells with a casting time of 1 action, but were not for swift casting time. It could be an omission, but it would be simpler to just state all spells if that was what they wanted.
2) Actions that do not provoke AoOs also do not require Concentration rolls for distraction as a general rule.
3) Actions that require your full attention can be distracted, but actions that do not require your full attention do not.
"You must make a Concentration check whenever you might potentially be distracted (by taking damage, by harsh weather, and so on) while engaged in some action that requires your full attention. Such actions include casting a spell, concentrating on an active spell, directing a spell, using a spell-like ability, or using a skill that would provoke an attack of opportunity."
4) Every single free action listed in the book states Attack of Opportunity: No.
Cast a quickened spell
Cease concentration on a spell
Drop an item
Drop to the floor
Prepare spell components to cast a spell
Speak
"Free Action: Free actions consume a very small amount of time and effort. You can perform one or more free actions while taking another action normally."
Now personally, I do not consider swift and free actions to require your full attention. Much of the text here indicates the opposite of your conclusion.
It is apparent that the designers consider free actions to not take your full attention.
It is also apparent that the designers considered standard actions and full rounds actions as the type of "attentive effort" actions that you can often be distracted on.
However, I agree it is not crystal clear. Depending on which rules you focus on determines how you interpret it.
You chose one rule "spells can be disrupted" as the important rule. Another DM can chose others rule "while engaged in some action that requires your full attention" and "if an action wouldn't normally provoke an attack of opportunity, you need not make a Concentration check to avoid being distracted".
That doesn't make your rule proof positive and the other rules not. You might consider your rule the specific rule. Another DM might consider your rule the general rule and the "full attention" rule as the specific rule (i.e. spells that do not fall under the full attention rule do not fall under the distraction possibility of the general spell rule).
But, BOTH rules are written in the rules and neither can be ignored when discussing rules.
