Your approach is somewhat ... unorthodox. Why don't you let
the LDAP server sort and filter? A few more details about
your XML and the whole problem wouldn't have hurt either.
I'll fill in any blanks, which may or may not have something
to do with your question.

Anyway, assuming your XML is more complete as
 <whatever>
   <supplementaryData> ... </supplementaryData>
   <searchResults>
     <searchResult>
       <employer>foo</employer>
       ...
     </searchResult>
   </searchResults>
 </whatever>

then try
 <xsl:template match="whatever">
   <xsl:apply-templates select="searchResults/searchResult>
     <xsl:sort
  select="*[name()=current()/supplementaryData/sort/sortField[1]]"/>
     <xsl:sort
  select="*[name()=current()/supplementaryData/sort/sortField[2]]"/>
  </xsl:apply-templates>
 </xsl:template>

Feel free to post your problem again with more details if this
doesn't match it.
