Publications of scores doesn't happen any more, atleast for the exams similar to the gaokao, which would be the JEE. It happened only for localised exams AFAIK, where almost all applicants were local, and the pool was small enough to be printed on a newspaper. In the pre internet era, it might have been necessary though, since it wouldn't have been possible to mail all scores and expect perfect delivery in the rural parts of the country. But the internet has ensured almost all test results are online now and not published openly.
