Wouldn't you have to mention unorder once for each variable binding in a 
query like the following one?

FOR $sp IN document("sp.xml")//sp_tuple,
     $p IN unordered(document("p.xml")//p_tuple[pno = $sp/pno]),
     $s IN unordered(document("s.xml")//s_tuple[sno = $sp/sno])
RETURN
    <sp_pair>
       $s/sname ,
       $p/descrip
    </sp_pair> SORTBY (sname, descrip)

Or am I missing something here?
