What you are saying here is, "Sort using all COLUMN children that have a 
'value' attribute."  This doesn't take into account the value of @value, so 
the sorting is effectively useless.

As you might have guessed, the <xsl:sort/> here is where you need to specify 
on which column to sort.  What you really wanted to say is, "Sort using the 
COLUMN for which @name is equal to the user's desired column, and sort using 
the value of @value from that COLUMN".

This is pretty simple to do:

<xsl:sort select="COLUMN[@name = $the-column-name]/@value"/>

A previous responder posted a similar solution, but forgot the '/@value'.  
Without the '/@value', the sort will proceed using the text value of the 
<COLUMN/> element, which is empty and obviously not what you want.
