I could only see one way to reorder -- a certain physicality.
I printed it and labeled sections pre or post or now or extra. Then I arranged all the marked pages as they were printed. Then I chopped them into sections pre, post, now, extra. After that, I put each section into their own chronological order. Finally, four piles emerged, each in order. I then went back to my document and cut and pasted a new draft. It lacks connective tissue but is roughly in place.
