Add option "bearing". When set to :line or :spherical it returns the bearing of the record from the search point, i.e. if the record is due north you'll see 0.0 returned. :line is a straight line, :spherical is the shortest path where the bearing between two points varies with distance to take into account curvature of the planet.
