afd19ebd61 Use super for imports in script module (Tobin C. Harding)
Pull request description:
In the `script` module we currently import `script` types using the fully qualified path, as recently discussed code is easier to maintain if we use `super` when `super != crate`.
Internal change only, no external changes.
