The script or automator workflow should:
1. Find all items in a *particular list* in [url removed, login to view] which were last edited more than N days ago
2. Copy them into another particular list
3. Delete the ones in the original list
The script should be clear enough that I can change the names of the lists and the number of days.

I've tried to simulate some operations needed to complete your task and think it's possible. I can start right now with low budget just for fun. AppleScript is always fun. :)
