You're right, the list of workspaces is being sorted. So my point about
number of screens should be about the number of workspaces, and nobody
ever has a single workspace. So the problem is purely academic. But here
is how the whole thing looks:

myXineramaSorter = do
    srt <- getSortByXineramaRule
    let prm (one:two:rest) = two:one:rest
        prm x = x
    return (prm . srt)
