If you look at the high scores, it's by resourced used. The top scores are in the 200,000-300,000 range. You're in the 10,000,000 range. My best was in the 5,000,000 range. I am not even sure how that is scored - I think it is a combination of the santas you use (times some factor) plus the time. So, less santas and faster = better score.
Geeze I am useless today...
