Technically it should. That code was written by David Kohel in 2005 -- one of the first contributions to Sage -- so don't be surprised if it is crufty. Writing a fast general finite-dimensional algebras arithmetic class sounds like a good project to me. Doing it in Sage (over wrapping GAP) has the advantage that it would work over any base ring. What functionality does the Magma version provide?
