I think I've tended to think of scripts as documents. Typically when I use it I'm describing to another programmer the name of a file (document), as in "Use the calculator(.py) script" or what have you.
While I'm sure I've used the term interchangeably with program as others have mentioned, I tend to use it to identify the names of specific language files. And as others have mentioned, they're all more or less programs when it comes down to it.
