Scout scopes are intermediate-eye-relief scopes designed to be mounted ahead of the action, more or less where the barrel-mounted rear sight usually is. The idea originated (I think) with Jeff Cooper, who drew up a set of specifications for what he called a Scout Rifle, and one of the specs called for this type of low-magnification scope. It lets you reload from the top of the action very easily, and if you can shoot with both eyes open it's a very fast system. I've had a Savage Scout and now own a Steyr version. Very cool guns. I've also found that the long eye relief of these scopes makes them useful for mounting on things like TC Encore rifles and H&R/NEF guns, as it puts them in front of the exposed hammer and allows low scope mounting without interfering with manipulation of the hammer. They take some getting used to, and I'm sure they're not everybody's cup of tea, but they're definitely worth a try.
