Deleting Old Backup Files - What am I doing wrong?

Hi,
I've just given up using Folder actions and now testing Hazel. One of the rules I've set should be pretty common:
1. given this folder (OmniFocus backup)
2. if the file has extension ofocus-backup (just to make sure I'm not selecting other files)
3. if date created is not in the last 1 month
then Move it to Trash
Basic, right?
Well, when I triggered this Rule all the backup files in the folder where deleted even if some where created today. So, what am I doing wrong?
