N.A.S.T.Y. Xstats - State buffs?

Good evening!

I'm currently using http://forums.rpgmakerweb.com/index.php?/topic/998-nasty-extra-stats/ in order to add a number of simple stats to my game (like Armor Class, a value for determining if someone gets hit or not, compared to the attackers hit roll and bonuses) and I'm having a bit of trouble with States.

I'm trying to figure out what I would need to change in order to be able to use the same 'note tags' as outlined in the Script to apply stat buff with items, to apply to states, so that I can have casters use spells that buff or debuff some of these extra stats by a set amount (not a percentage).

Having a devil of a time figuring out what would need to be done, or if I need to look for a different script altogether...
