These can be loaded up in single player custom matches, but you do have to complete the match. So change the settings and do this...
Capture the Flag set the score to 1 & capture it Oddball set the score to 1 then hold the ball for a minute King of the Hill set the score to 1 & sit on the hill Race complete a single lap then run around to all the capture points.
