Here's some more information on League Play:
Source : Call of Duty ELITE
League Play is a new feature introduced by Call of Duty®: Black Ops II that allows you to compete against similarly skilled opponents as a solo competitor or as a league team. Leagues are broken up into individual Series with different rulesets. Placement matches at the start of each Series determine your skill level by matching you against a spectrum of other players.Your performance in the placement matches grants a hidden skill level that determines your Division placement. You are placed within a Subdivision of that Division, and compete for Ladder Rank in the Subdivision Ladders. Winning a match earns you Ladder Points that help you climb the ladder, while losing a match results in lost Ladder Points. Your goal is to finish with the best rank by the end of the league season.
