i don't think you can do what you want.
in gql condition, you only have access to
__key__, which i bet is some hash of
kind + keyname + ...
so, keys_only query, then scan results.
or add another string prop and then
use some trick like
q.filter('key_s >=', u'_block\u0000')
q.filter('key_s <=', u'_block\u9999)
