Yes, PyTables is using Pyrex in order to link with HDF5 functions.

What I'd do in order to implement dimension scales is something like:

=2D Study the dimension scales API from HDF5 site:

http://hdf.ncsa.uiuc.edu/HDF5/hdf5_hl/doc/RM_hdf5ds.html

Do some tests in C, if needed

=2D Study the best API for PyTables: How are you going to link with DS?
Are you going to support several DS per dimension? How indexing with
new scales would be accessible?

=2D Look at the hdf5Extension.Array object and try to attach the DS there.

=2D Try to extend DS to EArray and CArray objects (should be
straightforward)

If you have more time and want to make your patches easily integrated
in PyTables.

=2D Add test units

=2D Add docs

All in all, it seems like a lot of work, but like everything else,
that depends on your priorities :-)

Cheers,
