Can you confirm that the version of VSC you're running is VSC 2.1.2? If it is not, could you do an inplace upgrade to VSC 2.1.2, repeat the script, and provide the output?
We've also got VSC 4.1, which includes many more features and API's updated to provide additional functionality and support for vCenter 5.0, if you'd like to test the P&C API's from VSC 4.1, you can find the download and documentation here.
Let us know how it goes!
