Nathan -

One thing I have discovered about the wing textures...

The FSX 727-200's do not appear to use the textures called "727_200_4_T" or "727_200_5_T"...instead they use "727_100_4_T" and "727_100_5_T".

I found this out by renaming the wing texures on an All-Nippon 727-200; once I renamed them the red circles and aircraft numbers magically appeared on the wings!  Try renaming yours and I bet it will work for you.
