I just tried with a slightly modified test backend with SANE_TYPE_INT
and the range looks ok. Are you sure that this is not related to the 
"range->max = s->boundaryx - 1;" you use when initializing the
ranges? Can you add a DBG in sane_control_option that prints range.max
for the option that's currently read? Together with the output of
scanimage it should be possible to find the source of the problem.

Bye,
