These are not "scripts" per se. They are compiled programs that must be installed on the server. I suspect that many shared hosts, such as hostgator, will not have them all installed, even though none of them are particularly uncommon.

That said, any remotely competent admin should know what those programs are, and they should be able to give you a simple yes or no if they're available. If they're not, I would seriously doubt that they're going to install a new program on the server just for one customer, and it might be against their rules for security reasons.
