Edit: Lost the race to Re: Need a regex.., which is also slightly better :)
Try a more grouped approach:
First the start of the line: ^
then an optional + or - sign, with the + enclosed in [] to avoid interpretation: ([+]|-)?
then 0-3 digits: [0-9]{0,3}
then an optional group of a period followed by 1-3 digits, with the period escaped in another way to avoid interpretation: (\.[0-9]{1,3})?
and finally the end of the line: $
