Spring Attack didn't change very much in the conversion, and not at all in that respect.
It's the standard action that changed.

Correct. But since the wording for spring attack did not change much, it works much differently since movement and standard actions became more distinct. The spring attack rule as written in 3.5, as you said, means that you can ME plus move/attack/move.
Either the designers knew the effect of changes (overrun was clarified and rideby attack is specific about a charge and double moving) and opted not to change spring attack thus it works differently or it was a conversion error. Could be either, most likely the latter. But being literal a house rule is needed to make spring attack work like it did in 3.0.
Clarified HR Version
SPRING ATTACK [GENERAL]
Prerequisites: Dex 13, Dodge, Mobility, base attack bonus +4.
Benefit: When moving on the ground, you can take a move action (including
jumping or tumbling) and another standard action at any point during the
move. You cannot take a second move action during a round when you make
a spring attack. Moving in this way does not provoke an attack of
opportunity from the defender you attack, though it might provoke attacks
of opportunity from other creatures, if appropriate. You can't use this
feat if you are wearing heavy armor. You must move at least 5 feet both
before and after you make your attack in order to utilize the benefits of
Spring Attack.
Normal: Without this feat, you can only take a standard action either
before or after your move.
Special: A fighter may select Spring Attack as one of his fighter bonus
feats.
