	Fixed the bugs in the ORDER BY logic:</p>
<ol>
	<li>
		The DESC modifier was incorrectly propogated to the result of the subsequent sort conditions during evaluation</li>
	<li>
		Ordering was bailing out early when one/both conditions evaluated to null/error without deferring to subsequent sort conditions which meant rows with nulls/errors in their conditions were only partially sorted</li>
</ol></td>
