Assuming you can't get a cleaned up export from the "Pro Tool" who recorded it, you might try something like this:
1. Import all the tracks and archive everything.
2. Un-archive one set of related tracks/takes (assuming you can figure out what belongs together

).
3. Select the clips from
all but one of the related tracks, and copy-paste special to the un-selected track using the Paste to One Track option (make sure to set the Now time correctly for pasting if not 1:01:000).
4. This will drop each of the pasted tracks into its own lane (I could be wrong, but I don't think there's a way to do this with drag 'n' drop).
5. Show lanes and click the highest numbered take in the track with the comp tool to make that the active take, muting all others.
6. Delete the copied tracks and save the project as a new version in case you need to backtrack at some point.
7. Repeat 2-6 for all the other groups of takes.
8. Have a beer... or two.
9. Start auditioning takes in each track to figure out what's what.
