I'm pretty sure you don't lose turns if you forget to activate the script for a few turns. I've seen a couple people complaining about not getting Polybian Reforms that didn't get it come 210 BC, then they activate the script to only move back to the 240 BC period.
Anyways, a few turns shouldn't hurt you, but any longer will break the AI. Without the script, I'm pretty sure the provinces the AI takes won't get their governments and barracks. They'll be broke all the time. So you'll have a really easy time killing off enemy factions this way.
