Turn off v-sync and you'll be above those numbers most of the time. If you don't know how, go into your drivers, e.x. right clicking your desktop and going into the nvidia control panel if you have a nvidia driver, and turning off vsync. If that's off, I'm pretty sure Skyrim has vsync enabled while you play, so turn it off.
The thing is that skyrim is not optimized for 60fps+... the physics goes nuts and characters are flying all over the place... actually use a 120hz monitor but i have to cap the framerate with msi afterburner to avoid that..
