I got it working by adding an element <summed> before
the <xsl:for-each select="ratios"> and using

 <xsl:apply-templates
select="msxsl:node-set($multiSum)/summed" />

and the following template

<xsl:template match="summed">
  <xsl:for-each select="number">
    <xsl:sort data-type="number" order="ascending"/>
      <test><xsl:value-of select="."/></test>
	<xsl:if test="position()=last()">
	  <max><xsl:value-of select="."/></max>
	</xsl:if>
  </xsl:for-each>
</xsl:template>
