You should do what I meant here, not what I wrote, unfortunately there
is not much correlation between the two, so I'll rephrase.

If you are doing it in one pass, then you want

  select="string-join(for $i in $ORDER_BY_TOKEN return *[local-name()=$i],',')"/>

If you are generating a stylesheet you want

<xsl:element name="xsl:sort" 
  select="concat('string-join((',  $ORDER_BY,  ')'','')')"/>
