What I was pointing out is that for the series 7, it's not quite a different order at all. Rather, the start of TPO3 may very well take place before ATCM. The bulk of the story, where the actual plot takes place, still takes place after ATCM. It merely starts a little earlier, and gives us some context on the perspective of Amy and Rory on their travels with the Doctor.

I do not think there is any indication in-universe, taking production errors into account, for the Seventh Doctor serials you mentioned taking place out of order. "Hints" are not enough to justify going specifically against broadcast order. As you've stated yourself, the issue at hand is that they shifted around the order and did not make edits to accommodate this, leading to inconsistencies. Those inconsistencies are nothing more than production errors, remnants of the original intended order of the series which was not the final one.
