You have to write your own. There's one in the "Colors and Levels" menu 
item in my Blocks game. This is the script of the scrollbar (there are 
only 3 positions):

on mouseUp
   setLevelValues
end mouseUp

on setLevelValues
   put the endvalue of me div 3 into theSegment
   put the thumbpos of me into thePos
   switch
   case (thePos < theSegment)
     set the thumbPos of me to 0
     break
   case  (thePos < theSegment*2 + 10)
     set the thumbPos of me to the endvalue of me div 2
     break
   default
     set the thumbPos of me to the endvalue of me
   end switch
end setLevelValues

I forget why I added 10 in the second case, but it had something to do 
with esthetics.
