How to make the AI attack certain provices?

[makute]

Hello everyone! It's been ages since my last visit

I came back to SS from a very long hiatus, and need some help editing the AI script to make it attack certain provinces. Specifically, I need Aragon to attack Bordeux if they can't reach Zaragoza (which I snab from them everytime) instead of just sitting there twiddling their thumbs. I recall doing something similar years ago, but can't find the thread where it was explained.

Thank you all in advance and have a nice day.

Edit: To be precise, I'm not talking about luring or tricking the AI into attacking a province or another Faction. I'm talking about the script that controls the decision-making process of the AI and assign weight to the available rebel regions at the start of the game, so every AI faction "aims" for certain regions above others.
