%client.incScore(%score); I think
For creating minigames auto on my server I simulated open GUI, Fav 1, Click "Start". With the method for "no games except admin's". Use %client.minigame and do a loop through all players and set their minigame to that. Minigames are scriptobjects which have variables and some code but nothing else if you want to create them manually, use (F11 ID).client.minigame.dump(); when "hosting" a minigame.
