A mobile user reports that interwiki search results come before normal results for them.
There is no interwiki search on m.wikipedia.org (nor full text search at all), so the user must be talking of the desktop site; indeed, if you take a busy result page and shrink the browser window, you can see that in the end the right div comes before the left div.
Should be trivial to switch the two HTML blocks.
