A stake mark that is not on the slot will merely increase the turning friction a bit, but presents no problem to a well-fitted screwdriver, properly applied. The slot itself has been marred at a later date as a result of using a poorly fitting screwdriver to remove the screw - look at the burr on the left side of the slot, towards the stake mark. When the screw was tightened up, the slot then turned past the stake mark, as you can see in the photo. This is not surprising, as even the best matured wood will still shrink a tiny bit over a century!
