这段代码可以保证数据的一致性吗

function updateZsetScoreWithLua($key, $member, $increment) {
    global $redis;
    $luaScript = "
    local member = ARGV[1]
    local increment = tonumber(ARGV[2])
    local zsetName = KEYS[1]
    local originalScore = redis.call('ZSCORE', zsetName, member)
    local newScore
    if originalScore then
        newScore = math.floor(tonumber(originalScore)) + increment
    else
        newScore = increment
    end
    redis.call('ZADD', zsetName, newScore, member)
    return newScore
    ";
    return $redis->eval($luaScript, [$key, $member, $increment], 1);
}
