How to add placement and elimination points for a zone wars map?

Just like the title says. If someone would be able to just give a breakdown of what I have to do that would be great.

My goal is for in each round to have my 32-player map give 1 point for every placement and 2 points for every elimination and store these points throughout the game on the leaderboard. Thanks for any help.

did you figure it out? im trying to do the same thing
