I've never tried to run a comparison on two files that were generated by code. By default they would not be "genetically" related which is the basis for comparison.
The original Compare Projects utility did use the Unique ID as the reference. However, it had some issues and it wasn't until (I believe) release of Project 2010 that the utility was finally "fixed". It is possible that it now uses the GUID as the reference, I don't know.
Since you are trying to compare two files generated by a macro you will most likely need to create your own unique reference so the files can be compared, and write your own compare macro like I did many years ago.
Good luck.
