There is currently a project that is in progress for getting (usual) oriented matroids into sage. It's still a work in progress, but an initial version is close to done. (See https://github.com/thecaligarmo/oriented_matroids for the project) Due to external time commitments, it hasn't finished as fast as I would have liked. (It's currently set-up as a package, but eventually it should nicely/easily be able to be integrated into sagemath itself)
