If you're referring to the " /gamerule enableOrcSkirmish true|false" command, it has been removed from the game.

Also, the wiki page on skirmishes says that hired units do not skirmish. I don't play as evil so I'm not sure if this is true or not, but if they do skirmish, it should be reported as a bug.
