Tackle this as a two phase transformation, phase one to do the summation and
phase two to do the sorting. Put  the intermediate results in a result tree
fragment, and process it for phase two using the xx:node-set() extension
function that comes with your chosen processor.

<xsl:variable name="phase1out">
  <xsl:apply-templates select="/" mode="phase1"/>
</xsl:variable>

<xsl:template match="/">
  <xsl:apply-templates select="xx:node-set($phase1out)" mode="phase2"/>
</xsl:template>
