You're right, they don't work. I'm sorry for suggesting things without testing it first.

I just read here that the Handheld.css is imported in MediaWiki installations on custom servers, but is currently not supported by Wikia. The Runescape wiki's "hack" is by using MediaWiki:Wikiamobile-menu (system message) to import the Handheld.css styles. So I'd suggest you to copy the code from their MediaWiki:Wikiamobile-menu over to your own MediaWiki:Wikiamobile-menu and then put your mobile styles inside Handheld.css
