Do not use t() in hook_schema(), this will only generate overhead for translators.
If the line declaring an array spans longer than 80 characters, each element should be broken into its own line.
A comma should follow the last multiline array item.
Added comment.
Variable $paid is undefined.
Messages are user facing text and must run through t() for translation.
