I finally tracked down the real reason, and it wasn't a bug with the AppEngine SDK. Rather it was with my Python interpreter, as I noticed it wasn't accepting arguments for any .py files. It turned out to be a registry error, located at [HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command] where I had to change the value from "C:\Python27\python.exe" "%1" to "C:\Python27\python.exe" "%1" %*

How this happened, whether it be the Python 2.7 installer, or maybe the AppEngine SDK, I'm not sure though.
