FWIW, the grass.script library doesn't require that GRASS uses the
same architecture (32-bit or 64-bit) as the Python interpreter.

The grass.lib library (and grass.pygrass and grass.temporal, which use
it) accesses the GRASS dynamic libraries from the Python interpreter,
so the Python interpreter has to match the architecture for which
GRASS was built.
