What is the best way to add scripts?

No, you dont need to append the version of the script to the filename, you can upload as many files with the same name as you want, they will not replace the old ones.
We store files with different filenames for each upload internally, and they will be sent to the end user with the original filename you uploaded.

Thank you very much for telling me that, I am sure the other scripters also like to hear it..
