The [x-y] type of expression is strictly for matching characters, not
numbers. To match a range like 100-60000 in a case statement, you would
write something like
1[0-9][0-9]|[1-9][0-9][0-9][0-9]|[1-5][0-9][0-9][0-9][0-9]|60000)
It might be simpler to use an if statement instead:
if [ "$VARIABLE" -ge 100 ] && [ "$VARIABLE" -le 60000 ]
