Turns out this doesn't work - the CSS Media Queries spec specifically requires serializing in sorted order and we have a test to that effect:
http://dev.w3.org/csswg/cssom/#serializing-media-queries
https://bugs.webkit.org/show_bug.cgi?id=39220

So it's down to violating the type system or writing my own sort.
