The advantage to receiver mounting is that there is no gunsmithing involved. Just buy the mount and screw it on. The other advantage, use of a higher power scope, you eliminated from consideration. The disadvantage is the comb height is set for iron sights so you will have to lift your cheek off the comb slightly to look through the scope.
An advantage to the forward scope is that it adds a bit of muzzle heaviness which some of us prefer.
If you go with a Scout scope, make sure you get it low enough or you will not get the benefit of handling speed that is the point of this whole Scout concept. You may need more than rudimentary gunsmithing to achieve this, but it is possible and is worth the effort. Even with a comb height set for irons this is possible as the barrel out there is lower than the receiver, allowing more space for mount and rings.
