No it's not a typo, the <sample> nodes may appear in any order within each
<row> node so that the order in the first row might be Sample 1, Sample 2,
Sample 3 but in the next row it could be Sample 2, Sample 3, Sample 1.

Thought: Is it possible to do a sort within each row so that they are all
in the same order, alphabetical order perhaps?

Sure. Something like
<xsl:for-each select="samples">
	<xsl:sort data-type="text" select="label"/>
	<TD>							
		<xsl:value-of select="displayval"/>
	</TD>
</xsl:for-each>
