I think you can use an int for the ords? Now that we have subord,
when you get negative index back from binary search, you can set ord
to -index-1 which is the "lower bound", and then as long as subord is
at least 1 it should compare correctly.
Also, in your 2nd pass, if the list is length 1 then you can
immediately set subord to 1 and move on.
In your first pass, in the "else" clause (when the value was found in
the next segment) don't you need to set subord to 0?
