Learning more about attribute value templates--when you can and can't use
them in XSLT--would be a good start.

There is no need, nor is it legal, to use an AVT in an XPath expression.  It
may not generate an error, but as you've discovered the content of the curly
braces are ignored.  There's also no need to enclose the variable within
quotes:

<xsl:sort select="MIB[@name=$sortby]" order="{$sortorder}"/>

(The order attribute does use an AVT, so that is unchanged.)
