  That requires that name() will always return the same string for two
nodes with the same name (same namespace URI and same local part name),
which is not guaranted.  IMHO you need, as Mike proposed it, the two
keys:

    <xsl:perform-sort select="$nodes">
      <xsl:sort select="namespace-uri()"/>
      <xsl:sort select="local-name()"/>
    </xsl:perform-sort>
