We've been correcting the images as we find them, so the rebuild probably isn't necessary for us. And I've noticed that IM seems to strip out the orientation & camera info tags when it resizes. So if it's resized first, there's no exif orientation tag to trigger the rotation. The only way I was able to track down the problem was by examining the few photos that were taken at low enough resolution that IM hadn't resized them as they were uploaded/stored on the MB. I used JPEGsnoop to see/analyze several of the weird photos. I've had a few users email me the original (untouched by IM) photos for comparison. The image quality ON SCREEN after resizing is ALMOST as good as the original. It's good enough to see most of the essential details, but not good enough for true archival/research work. If you'll give me your email in a PM, I'll send you a few if you want.

IMHO, the proper order of operations is: Rotate the full size photo if it contains an exif orientation tag, THEN generate the other views, with the largest view resized down to 1600W for storage after rotation to make the resulting image as large as reasonable for our available storage & bandwidth. Normally, 200x200 thumbnails are visible in the posts, and users can get progressively larger views by clicking on the visible photos.
