It may turn out that Mr Scott was already married, so they could not legally marry.
Anyways, I realize you are only looking for the marriage, but I wanted to point out that on another forum back in 2011, someone was searching for the exact scenario (as in, 262 Victoria Park Dr for a birth in 01 Mar 1925, parents living at 85 Albert St). If this wasn't you, I can dig the link out of my history so you can try to connect with this person.... maybe they found the answers to your mystery.
