I haven't dug into this, but I think MapServer pulls the features from

Frank,
I could be wrong, but my understanding is that MapServer reads the
shapes in the shapefile order all the time. If a .qix file is present,
then an array of bits is used to tag the shape ids to load, and then the
shapes are read in order of shape id.
Daniel,
Ah, and there is the danger of a theory without investigation. :-)
Best regards,
