Depending upon the version, you may be able to use the analytical functions (8.1.6+) to achieve what you want. I don't have a ready example, but the Oracle docs are pretty good. If you want a less elegant solution, use an inline query, sort by the reverse order (asc or desc depends on your requirements) and take the top 3. You can find examples of the Top-N approach on www.optimaldba.com/library.html. Either the Top-N Row or SQL Scripting Sorcery paper/presentation will have enough info to solve
the problem.
