I'd like to set a script similar to the very first script in this thread, i.e. adding money to a faction that captures a settlement. However, I want to add a different set of conditions:

For example, consider Jerusalem:
If a Catholic faction captures Jerusalem from a Muslim faction, it gets bonus money.
Otherwise, it doesn't.
If a Muslim faction captures Jerusalem from a Christian faction, it gets bonus money.
Otherwise, it doesn't.

So I need to check the faction that owned the settlement before its capture. Also, would I need to repeat this script for every faction, i.e. Moors, Egypt & Turks for the Muslims, and England, etc. for the Catholic?
