Well, 3 of the top 10 are admin; 3 try to balance the maps; 1 is a rehab map stacker; 2 are 50/50 map stackers (i.e. no admin on they stack); 1 always map stacks.  Most of the time there is an admin on and the 3 that balance will ask the admin to switch.  don't see why they would need a team swap option.  It would be nice if you broke the top 10 (or 5) you could only chose a certain team on certain maps.

I say zero out the scores.  If possible start a historic stat tracker that keeps overall stats.  I don't see many of the top20 leaving because there are relatively few servers that allow awps and consistently have a high player count.
