I also just ran the same series of tests with my D700 and added the Nikon 28-300 lens. The exposure results for the Tamron were identical with the D700. The 28-300 exposure results were close to the Nikon 70-300VR at 70 and 300.
I know this is not a very scientific test, but it appears that my Tamron is underexposing in aperture mode, but exposes correctly in shutter mode if there is "headroom" to adjust the aperture.
Appears that if I shoot in shutter mode, I will be okay...
