The canonical name for a rated scale (ie, bad 1 2 3 4 5 6 7 good) is a Likert scale. A default Likert scale would probably go -3 -2 -1 0 1 2 3. You would typically want to define the number of values (usually odd), start and end point or default to 0 as the middle, and text labels for min, max, and middle.
