This is a very cool script. It balances out the problem of players with less deaths and less kills being ahead of those that potentially did better. What would be really neat to see would be for the damage not to be based off of the physics. While this would complicate the script much more, it could be very interesting- e.g., a magnum kill would be worth more than a rocket kill.
By far, this is my favorite pack of netmaps. All the levels are skillfully laid out, with enough weapons to get the job done, but not too many as to make it look cluttered.
EDIT 1/21/10: I see that maps have been added without rockets. I would rate this a six if I could...
