Indeed, and although the ordering hasn't changed much over the years, typically it *has* been different between 32-bit and 64-bit CPU architectures.
Hence even without the randomization, Python code that erroneously has an implicit reliance on a dict ordering tends to break when run on a machine with a different word size to the one you wrote it on.
