You can use CPAN module, such as List::BinarySearch instead of writing code yourself.

Also, instead of using min and max you could use $array[0] and $array[-1] - the list is sorted.

Also, as far I can see, you check if value is out of bounds every time loop passes. You can move this check outside loop.
