If you count your parens , I think you'll discover that the indentation on
the final REST is misleading; clearer is:

        WHERE="beer not in (%s)" %
            c.SELECT("beer",
                FROM="serves")),
        REST="order by 3 desc")

and that explains why it thinks you specified REST twice:  you did <wink>.
PythonWin (or IDLE) should have shown you that when you hit ENTER on the
preceding line, though (they use the same auto-indent algorithm under the
covers, and it aligns the new line under WHERE).
