Should work - we have tests in the bioperl-live code for strandedness 
and bl2seq reports for blastn and tblastn.

in t/SearchIO.t
ok($hsp->query->start, 94);
ok($hsp->query->end, 180);
ok($hsp->query->strand, 1);
ok($hsp->hit->strand, -1);
ok($hsp->hit->start, 1);

I don't remember if this bug was fixed before 1.4 went out but 
SearchIO::blast parsing was definitely updated for several bugs since 
1.4.0 release.

Can you post a report and exact code that you are testing as a bug 
report to http://bugzilla.open-bio.org and someone can have a looksie.
