Well, according to this post which I linked to in my original post, the concatenation is done for "performance" reasons. As for why load.php imports occur prior to default CSS, I could see that being intentional. It allows the user writing the CSS to decide where to insert the custom CSS. Essentially, it allows the user to defer to default CSS during a selector conflict if they want to. However, if it is intentional, it should probably be mentioned on the help page. Based on the text there, it sounds like the two methods should yield identical results. - Edit:

Upon further thought, perhaps Wikia should implement a separate page for CSS imports (e.g. MediaWiki:ImportCSS and Special:MyPage/importcss). These pages could be placed before MediaWiki:Common.css and Special:MyPage/global.css. This would still allow for global imports through Special:MyPage/global.css as the preceding CSS would be nothing but imports.
