I also have not used ScanScore, but I have happily used another
program called PhotoScore Lite. The Lite version doesn't seem to be
available currently as a stand-alone program, and the full version
is expensive: $500 list. I've used the Lite version extensively to
make four-part arrangements for our small MIDI crank organ; see
https://www.neuratron.com/photoscore.htm 

The PhotoScore Lite version works well with good quality piano
sheet music, but will handle only a limited number of lines. There are
workarounds by using graphics editing or working from parts rather
than from a score, but that requires a variety of computer skills and
understanding the musical composition.

Because he has an orchestral score, Ben's job would require ScanScore
_Professional_ which costs $79 for a 1-Year license, not the simple
Lite version.

I would guess that ScanScore Professional could do the job, but
remember that musical skill and a "good ear" are required to "proof
read" the result as well as computer skills including scanning, and
the score pages might require a large size scanner.

Sheet music to MIDI software is still at the "for musicians" stage,
it's not like a simple "text to PDF" conversion job.
