They announced the coopertition award a few weeks ago -

Section 9 is titled "The Tournament". In past years, this has included information on matches, scheduling, the ranking system, game play rules (time outs, yellow/red cards, that sort of thing - nothing game-specific).
This seems to indicate that the coopertition bonus points aren't earned as something specific to the game, but something that is more related to the game/tournament structure we use every year. But the short answer to all of this... We won't know how to earn those points until Saturday.
My personal best guess - they're changing the structure of the game somewhat, giving us 3 alliances on the field at any given time, and you'll have opportunities to work together with inter-alliance combinations to achieve some bigger goal than you could do by yourself.
