Sorting on an attribute passed as a parameter from JavaScript

I think this problem probably has a simple solution. I have a web page with a 
JavaScript that passes a parameter to an XSL file so a sort can be performed 
using the parameter. The sort works with element names, but not with attribute 
names.

For example, given the following XML:

    <SCReg reg_num="04">EREG</SCReg>

when I pass "SCReg" to the XSL file as param1, the sort works correctly. But 
when I pass "SCReg/@reg_num," the sort doesn't work. 

Here's the sort code from the XSL file:

    <xsl:sort select="*[name()=$param1]"/>

Apparently this code doesn't work with attributes. How can I tweak it so it 
works with elements and attributes?

I should add that <xsl:sort select="SCReg/@reg_num"/> DOES work.

Thanks in advance!
Kathryn
