#zrevrangebyscore(key, max, min, withscores: false, with_scores: withscores, limit: nil) ⇒ Object

Return a range of members in a sorted set, by score, with scores ordered from high to low.

Examples:

Retrieve members with score ‘< 100` and `>= 5`

redis.zrevrangebyscore("zset", "(100", "5")
  # => ["b", "a"]

Retrieve the first 2 members with score ‘<= 0`

redis.zrevrangebyscore("zset", "0", "-inf", :limit => [0, 2])
  # => ["b", "a"]

Retrieve members and their scores with scores ‘> 5`

redis.zrevrangebyscore("zset", "+inf", "(5", :with_scores => true)
  # => [["b", 64.0], ["a", 32.0]]
