Currently, I believe, Special:MyPage/common.css takes precedence over MediaWiki:Common.css which takes precedence over MediaWiki:Common.css which takes precedence over Special:MyPage/monaco.css which takes precedence over MediaWiki:Monaco.css. The new skin will hopefully preserve a similar order of precedence. Use of "!important" in the CSS can make things confusing. Inline styles take precedence over all of those. Also w:Special:MyPage/global.css is in the mix there somewhere, but I'm not sure where.
