That wouldn't not be a kludge actually, since the SQL-99 standard does not allow ASC/DESC on GROUP BY at all. It is an extention in the MySQL server (see http://www.mysql.com/doc/S/E/SELECT.html), and basically it is a shortcut for exactly what you describe: an ORDER BY with the same fields as the earlier GROUP BY. I tried it too on a 3.23, and indeed it does appear to not be working. Contrary to what is described above though, there is no ordering at all in my output, not ascending either. So basically it is as you would expect it to be without any ORDER BY operation. Maybe the output others got was just sheer luck, as it depends on the order the server reads the data rows.... Anyway, I've sent a note to the developers about this, including a sample reproducing it.
