How about:

<xsl:variable name="uppercase" select="'ABCDE'"/>
<xsl:variable name="lowercase" select="'abcde'"/>

<xsl:template match="Root">
  <xsl:apply-templates select="A|B|C|D|E">
    <xsl:sort select="." data-type="number"/>
  </xsl:apply-templates>
</xsl:template>

<xsl:template match="A|B|C|D|E">
  <xsl:apply-templates select="/Root/*[local-name() =
translate(local-name(current()), $uppercase, $lowercase)]"/>
</xsl:template>

<xsl:template match="a|b|c|d|e">
  <no><xsl:value-of select="."/></no>
</xsl:template>

This sorts the uppercase elements and then calls apply-templates for the
lowercase namesakes.  It produces this output:

<no>30</no><no>40</no><no>10</no><no>50</no><no>20</no>

The last <no> is different to your example output, but I'm guessing
that's a typo.
