in other words you need random y between 125 and 160 and related scale
between 20 and 100 (or between 0 and 80 plus 20)
for clearity:

make it that way:
"random" = random(35)
"randomY" = random + 125
"scale" = int (( random * 80/35 + 20 ) * 100

80 = 100 - 20 and it is max related to max random 35 -> 80/35

you can also do that way
"randomY" = random(35) + 125
"scale" = int (( (random-125) * 80/35 + 20 ) * 100
