Imitarate: This is an issue with item and effects modifiers (Belt of Strength +1, Bull's Strength, etc). Innate modifiers (leveling ability score adjustments and epic ability score feats) are not affected and do not count towards the limit. The same is true with base skill gains (obviously) and feat-based skill increases (skill focus, stealth, etc).
This is hardcoded into the engine (the game does not recognize item adjustments greater than +12 and ignores effects adjustments greater than +12).

when it comes to Minimum modifiers Abilities can't go below 3. but you can't decrease a high ability with more then 30 points.

ability points can only decrease -10 step since patch 1.65, was changed when they fixed the DEX underflow bug.

Note: in patch 1.62 (and previous??) the DEX modifier can underflow below 0. ie score of 255 and below will then appear with uber AC as result. this is fixed with version 1.64

skill can also decrease up to a maximum of 50 ranks.
