Using GROUP_CONCAT and FIND_IN_SET you can do that.Check SQLFIDDLE.

SELECT *
FROM tbl t
WHERE FIND_IN_SET(t.value,(SELECT
                             SUBSTRING_INDEX(GROUP_CONCAT(t1.value ORDER BY VALUE DESC),',',3)
                           FROM tbl t1
                           WHERE t1.name = t.name
                           GROUP BY t1.name)) > 0
ORDER BY t.name,t.value desc
