OK, nice one Sundar. Lets take it a bit further. What if this XML would
contain also other @val's than A. For example:

<Root>
<Elem val = "B1"/>
<Elem val = "B2"/>
<Elem val = "B12"/>
<Elem val = "A1"/>
<Elem val = "A2"/>
<Elem val = "A21"/>
<Elem val = "A3"/>
</Root>

In this case your solution would not work. Instead the correct one
would be

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html"/>

<xsl:template match="/">
  <xsl:for-each select="./Root/Elem">
    <xsl:sort select="substring(@val,1,1)"/>
    <xsl:sort select="substring(@val,'2')" data-type="number"/>
    <xsl:value-of select="./@val"/>
  </xsl:for-each>
</xsl:template>
</xsl:stylesheet>

This way the result would be:

A1 A2 A3 A21 B1 B2 B12
