Troubleshooting a sort

Hello,

I'm trying to sort an XML file--here's a representative record:

<SAVEIdea>
      <SAVE_ID>25</SAVE_ID>
      <date_submitted>01/14/2004</date_submitted>
      <employee>Kathryn Grant</employee>
      <department>OPE</department>
      <idea>Buy faster printers.</idea>
      <status_history>
         <status timestamp="1/20/04, 4:33:13 PM" userID="GRANT01">Submitted for supervisor review</status>
         <status timestamp="1/25/04, 9:21:45 AM" userID="GRANT01">Submitted for CFO review</status>
         <status timestamp="1/29/04, 6:12:22 PM" userID="GRANT01">Approved</status>
      </status_history>
   </SAVEIdea>

The name of the tag by which I want to sort is passed as a parameter to the XSL file from a web page using javascript. Below is the XSL, and the sort works for every column except the Status column (last column). 

As you can see in the XML file, the status tag is a level deeper than the other tags I'm sorting on. In addition, I'm pulling the last of all the status tag. So how can I make the status sort work?

Thanks in advance!

Kathryn
