In my experience, it does the ORDER BY and then the LIMIT.
Or, at least, that's what comes out of the browser.
They *MIGHT* be doing something so that after they find the first 10 records
(or whatever your LIMIT is) they *QUIT* sorting all the others, since
there's not much point to sorting records you ain't gonna be getting anyway,
is there?
