is this really tough?

I would like to sort the following XML file based on the displayposition.
I am printing the value and displayname. 

Here is the XML File I have used:

<?xml version="1.0"?>
<o>
        <com>
                <hereyougo>
                        <first displayposition="4"
displayname="raman4">4</first>
                        <second displayposition="1"
displayname="raman1">1</second>
                        <third displayposition="3"
displayname="raman3">3</third>          
                        <fourth displayposition="2"
displayname="raman2">2</fourth>
                </hereyougo>
                <imaycome>
                        <four displayposition="4"
displayname="raman4">22</four>
                        <five displayposition="1"
displayname="raman1">33</five>
                        <six displayposition="3"
displayname="raman3">44</six>                   
                        <firvi displayposition="2"
displayname="raman2">11</firvi>                 
                </imaycome>
        </com>
</o>

This is the output I expect:

raman1 1 33
raman2 2 11
raman3 3 44
raman4 4 22

The o/p I am getting:

raman1 4 22 
raman2 1 33 
raman3 3 44 
raman4 2 11 

The XSL File I used  to process This :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output method="html" indent="yes" />     
  <xsl:template match="/">
 <table>
 <xsl:variable name="y" select="o/com/*" />
     <xsl:for-each select="$y[1]/*">
        <xsl:sort select="@displayposition"/>
      <xsl:variable name="x" select="position()" />
      <tr>
      <th>
        <xsl:value-of select="@displayname"/>
      </th>
        <xsl:for-each select="$y/*[position() = $x]">
                <xsl:sort select="@displayposition"/>
          <td>
            <xsl:value-of select="." />
          </td>
        </xsl:for-each>
      </tr>
    </xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>

Possible Error:

<xsl:sort select="@displayposition"/> in the second <xsl:for-each > is not
working.

Pls help me out.

thanks and regards,
