I have created an interface that uses GetSpeciesList to perform a data search of a circular region. Everything works fine except that I seem unable to influence the order that species are reported using the attribute of sort="Scientific" or sort="Common". The order returned is always the same and pseudo-taxonomic (but not right). Here's a small example from returned data:

Erinaceus europaeus (West European Hedgehog)
Talpa europaea (European Mole)
Mus musculus (House Mouse)
Lutra lutra (European Otter)
Muntiacus reevesi (Chinese Muntjac)
Rattus norvegicus (Brown Rat)
Sciurus carolinensis (Eastern Grey Squirrel)
Aglais urticae (Small Tortoiseshell)
Aricia agestis (Brown Argus)
Inachis io (Peacock)
Ochlodes faunus (Large Skipper)
Pieris brassicae (Large White)
Polygonia c-album (Comma)
Thymelicus lineola (Essex Skipper)
Anthocharis cardamines (Orange-tip)
Celastrina argiolus (Holly Blue)
Gonepteryx rhamni (Brimstone)
Nymphalis antiopa (No common name)
Polyommatus icarus (Common Blue)
Maniola jurtina (Meadow Brown)
Melanargia galathea (Marbled White)
Pyronia tithonus (Gatekeeper)
Pararge aegeria (Speckled Wood)
Gasterosteus aculeatus (Three-spined Stickleback)
Cottus gobio (Bullhead)
Oncorhynchus mykiss (Rainbow Trout)
Phoxinus phoxinus (Minnow)

Does this make sense, or should I continue to look for the bug in my code?

I would quite like (correct) taxonomic order, but this still doesn't seem to be an option?
