I'm not saying that Superman would win by any means. Don't get me wrong the Lobo scan is certainly not one of Sup's greater feats, however knocking someone into orbit seems to be a little tougher than beating them around on the ground. As far as the Anti-force blast. . .not sure how strong that attack is, but we all know Sup's has taken multiple hits from OE and come back for more.
Once again not saying sups woud win, but I think given enough time that it would go either way.
