I think you should, for several reasons:

- People expect sorted word lists to be sorted by symbol
   rather than by sound.
- There is still quite some uncertainty about phonetic
   values of PIE phonmes, so a reference work should IMHO
   play it safe.
- Most importantly if you start from a certain daughter
   language and try to guess at the PIE form of a word you
   may not be able to guess which PIE guttural it contains,
   so it makes sense to have all of *k *ky *kw sorted as *k.
- In fact I think that it would be best to use bi-level
   lexicographic sorting, so that all symbols derived
   from/similar to/equivalent to a certain Latin letter
   should sort as that Latin letter, since that would
   free readers from remembering a modified/extended
   sort order most of the time. See 
<http://cpan.uwinnipeg.ca/dist/Sort-
   ArbBiLex> / <http://cpan.uwinnipeg.ca/htdocs/Sort-
   ArbBiLex/Sort/ArbBiLex.html> for both the tool and
   the concept!
