Interesting question.

If you look at the spec's example of numbering 
(http://www.w3.org/TR/xslt#number), you'll see that position() within 
the body of a for-each reports the position *after* sorting. So that's 
one approach -- for-each over the sorted set, test position(), and only 
apply-templates if the position is within the range you're interested in.

There are probably a dozen other ways to accomplish this. I'd suggest 
checking the sorting section of the XSLT FAQ website -- wonderful 
resource! -- and possibly other related sections as well, to see if 
someone has contributed a more elegant solution.
