We introduce a relation on real conjugacy classes of SL(2)-orbits in a Mumford-Tate domain D. The relation answers the question when is one R-split polarized mixed Hodge structure more singular/degenerate than another?. The relation is compatible with natural partial orders on the sets of nilpotent orbits in the corresponding Lie algebra and boundary orbits in the compact dual.
