Steve, you haven't asked for suggestions on this, and so it may be invidious to
contribute, but anyway if it's helpful here's mine.

I'd use Word for this job.
Currently there are no better tools for final editing of prose than its Comments and
Track Changes features, in my view. (That's not just my view, but also the view of
several other writers of my acquaintance.) I'd probably "chunk" the 100 pages up with
Scrivener, get the overall structure right and then export in rtf to handle the
re-write in Word. To avoid the dreaded Word crash risk (although that's probably now
much-diminished or non-existent) I'd tackle only a few sections at a time. Finally
I'd probably re-export in rtf to Scrivener to re-combine. (This all assumes there are
few or no illustrations, or they could be added as a very late step.) Word in either its
Mac or Windows manifestations would do, but I think the Windows version would be
better in certain respects. (See David Hewson's blog for his reasons.) That's what I
use Parallels on my Mac Mini for.

This reminds me of this previous thread we had on outliners for redacting text. I found Scrivener's Ctrl+K split function pretty handy for breaking down the text into paragraphs and eliminating or reducing them one-by-one.
