Efficient ranking system?

[Callum]

I'm working on a clan scores system where players can use !clanstats and !topclans (idea from XE european server). I'm currently using the GUPS gamemode, and want to add this feature on. How would I go about making it efficiently? Any chance I could use the current GUPS method of .ini files? Basically, I want to assign each clan a score value, and then pull up the data and give it a rank based on all the other scores.
