I could not do it either... exactly, so this was my attempt.
In the properties of the scrollbar, I set the Start Value to 1 and the End
Value to 3.
No matter what, the arrow that indicates thumbPosition did not "snap" to
the absolute position of 1, 2, or 3.
So I made a Plus and Minus button which contained this script

on mouseUp
  if the name of me = "+" then
       set the thumbPosition of sb "SB1" to (the thumbPosition of sb "SB1")
+1
    else
       set the thumbPosition of sb "SB1" to (the thumbPosition of sb "SB1")
-1
  end if
end mouseUp

That works, but not when dragging the actual arrow of the Scrollbar.
