When I do something like this I often just use a regular expression to
match the number. If the limit is simple, and the format consistent,
it's often simpler. e.g. for <120.0
score=(-|[0-9]{1,2}|1[01][0-9])\.
It's worth knowing this because sometimes (outside of shell scripts)
it's the only way of doing it.
