I think that you need to group first, and then sort the members of the
group. Something like:

<xsl:key name="elems" match="Elem" use="@GroupID" />

<xsl:template match="Root">
  <xsl:for-each select="Elem[generate-id(.) =
                             generate-id(key('elems', @GroupID)[1])]">
    <Group><xsl:value-of select="@GroupID" /></Group>
    <xsl:for-each select="key('elems', @GroupID)">
      <xsl:sort select="@Order" data-type="number" />
      <xsl:value-of select="." /> -
    </xsl:for-each>
  </xsl:for-each>
</xsl:template>

Cheers,

Jeni
