Patch: Selectable Script

I've never touched monster scripts so bear withme on the possible idiocracy of this question...

Do I understand that correctly about it going to the control list (and abandoning the monster script if it has one) while muddled/berzerk state? Does vanila do that anyway? Never really understood what something like muddle did to a monster normally (other than random the battle target between ally and enemies.)

In other words, am I correct in saying if using this, and monsters did have scripts, they would actually abandon the pseudo "intelligence" of a script for a random choice from a limited menu while confused?

Or am I lost and the game does that anyway?
