There isn't really a set of rules for deciding if a script is big or small or whatever but a couple of points to look at are the amount of code, the file size and the amount of features as well as the quality of the whole script (as in have they explored a lot of different avenues that are possible to go along with that whole idea).

Defining a script's size is not really important by any means, but for examples, the likes of Screenshot Sender, Message Customizer! Live and Now Playing are 3 big scripts as they all use interfaces to help with their many features and they all are quite large pieces of code.

Tiny and small script are the kinds of things that I just write to do a couple of small things to help me out, they usually consist of a couple of lines of code with no interfaces, just something simple to get the job done.

If you want any more information then just ask, this stuff really isnt important when it comes to scripts, it is more the features they offer and the quality of the code that the developer writes.
