Thanks for the offer.

For what it's worth, I'm getting this fixed in Koha; I just need to
write a test for it:

If the consensus is that the Dewey classification should be very
strict in what it allows (and there have only been a handful of folks
weighing in on this ticket, so who knows), then the real bug is that
we're not strict here. Should non-Dewey call numbers fall to the end
of the list if using the Dewey classification? Maybe have a fallback
to Generic as a sub-sort?
