A simple way is to do the sort in a variable first, then for-each over
the variable to produce your table rows.

<xsl:variable name="sortedRows-rtf">
  <xsl:for-each select="links/link">
    sort, xsl:copy etc...
  </xsl:for-each>
</xsl:variable>
<xsl:variable name="sortedRows" select="xxx:node-set($sortedRows-rtf)"/>

Then...

<table>
  <xsl:for-each select="$sortedRows">
    <xsl:for-each select="link">
       ....


Get the idea?

Whenver you have some multi-stage processing to do, just split it up
into variables, each one working on the previous one.
