Then you need an ORDER BY clause, maybe:

SELECT sw.swid, title, shortdesc, version, catid, count(dl.swid),warename
FROM software sw
LEFT JOIN downloads dl ON sw.swid = dl.swid
JOIN waretypes wt ON sw.wareid = wt.wareid
WHERE liveyn = 'y'
GROUP BY
sw.swid, title, shortdesc, version, catid
ORDER BY count(dl.swid) DESC
limit 20
