Perhaps a better way to phrase the question might be this: You can sort on
the value of functions intrinsic to XSL, such as position() or
substring-before() etc.  Is it possible to write your own "functions" as xsl
templates, and sort on the value returned from those?

Use a variable?

<xsl:variable name="sortkey">
  <xsl:call-template name="foo"/>
</xsl:variable>
<xsl:for-each select="/some/nodes">
  <xsl:sort select="string($sortkey)"/>
