Here is a short xslt that will just sort by PileNo and copy the exact xml to 
the result tree.  The sort is done in the first match template with the copy 
occurring after the sort.  Also note that you will want to set the data-type 
on the sort or it will try to alpha sort instead.  You could also transform 
it into a different xml document after the sorting occurs.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
version="1.0">
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:template match="PileCoords">
		<xsl:copy>
			<xsl:apply-templates>
				<xsl:sort data-type="number" select="PileNo"/>
			</xsl:apply-templates>
		</xsl:copy>
	</xsl:template>
	<xsl:template match="*">
		<xsl:copy>
			<xsl:apply-templates/>
		</xsl:copy>
	</xsl:template>
</xsl:stylesheet>

Hope this helps.
