Ben, I don't think you're going crazy, and I don't think you've got a faulty D7000. There is something strange going on though, which I haven't quite got a full grasp of yet.
There are a couple of things that don't look right: first I don't think you can set Hi or Lo ISO values in Auto ISO, and as Vlad says Auto ISO will not use a manually set ISO that's outside the range, so the use of Hi1 seems suspect, and secondly the exposures are terrible, I'd expect much better exposure in both circumstances if everything was working 'normally'.
Various exif viewers give different interpretations of the flash settings of your pictures. The Nikonians gallery says Manual mode, return light not detected. PhotoME says Flash fired, compulsory flash mode, return light not detected and Built-in, Comdr., and Fired, TTL mode. Opanda says similar things.
I don't know what your flash setting really was, but I think that the camera didn't know what was going to happen with the flash, and so it suspended Auto ISO operation and used the user-set ISO value for those frames. So, although Auto ISO is reported in the exif data, the camera did not know what was going to happen with the flash, and decided not to alter ISO from your chosen value.
Check your flash settings. Maybe manual or commander mode is confusing things. It's still possible that the camera's faulty if it really isn't detecting the flash return light.
