Hi Simon, The Sage documentation says an unknown term ordering is just passed to the Singular. So in this case, 'M(a)' should be passed to the Singular. Since the Singular knows 'a', the ring declaration should work. I suspect that this is a bug of Sage.
Anyway it will be great that the matrix ordering is included in Sage natively.
