Flurry restricts what weapons you may use to flurry - it says nothing about what else you might be able to do during the round.
You need to be more precise. Flurry restricts what weapons you may use "when using flurry of blows". Additionally, "The monk can’t use any weapon other than a special monk weapon as part of a flurry of blows."
So, your argument requires that a monk is using flurry of blows and then not using flurry blows, in the same round,
in the same full round action. I say that's hogwash because
1. It's a single full round action, not multiple actions.
2. You can intersperse the natural weapon attacks with the other attacks, in any order (although iterative attacks must be taken in order, there's no other restriction). This means I could attack with an unarmed strike (now using flurry of blows), attack with my tail (not using flurry of blows), attack with another unarmed strike (using flurry of blows again), etc.
3. The rules that allow those secondary attacks combine them.

It does say, "A monk must use a full attack action to strike with a flurry of blows.," but that does not limit what ELSE you might be able to do either as part of your full attack or in addition to it. The only limits are those imposed by what you may do as part of, or in addition to, a full attack.
You need to be absolutely clear what you mean by this. Are you suggesting (a) there is a flurry full round action following some other type of action, or (b) just a flurry full round action coupled/interspersed with something else?
Whenever you say "in addition to the full attack" you are wrong because I've already shown that the secondary weapons are combined with the full attack (full round action) and therefore part of it.
