Hi Max,

I'm not aware of anything in the feature table specification
about the order of the feature qualifiers (the "tags" like /note
and /product). See http://www.ncbi.nlm.nih.gov/collab/FT/

I suspect BioPerl is using a hash (Biopython uses a dictionary)
for the feature qualifiers, which would discard the order.

Why do you care about the order?
