You don't need the evalue function, or name() here.

so just use
	<xsl:sort select="column[@name=$sortKey]"/> 
where $sortKey contains either "FirstName" or "LastName". 

You've given the columns @name attributes, so you don't need the name()
function.

On the other hand, if you had
<row>
	<columnA>foo</columnA>
	<columnB>bar</columnB>
</row>
and you wanted to sort either on columnA or columnB, you'd use
	<xsl:sort select="*[name()=$sortKey]"/>

HTH,
Tom SW
