I'm by no means a Babel expert but I don't think this information is
currently accessible (checked the import_cldr.py script).
For a start, we need to know if this information is contained in the
cldr data: http://unicode.org/Public/cldr/1.9.1/
If so, please file a ticket. Bonus points if you name the actual
attribute where this is stored.

Bad news is that Babel does not expose this in any way so this needs to
be implemented. Can you search existing tickets (if such a request
already exists) and create a new ticket if there is no such ticket?
