顺序列表根据阵列的信息排序

我想做的是根据数组中的信息重新排序数组列表。例如，我的列表可能有20个Long[]数组，我想按最高总aps和最低总时间排序。我尝试了几件事，但遇到了麻烦。任何帮助都将非常感激。

public List<long[]> Reorderedlist()
{
    _timeKeeper._timeKeeperControls controls = new _timeKeeper._timeKeeperControls();
    List<long[]> returnList = new List<long[]>();
    List<long[]> listToReOrder = new List<long[]>();
    listToReOrder = controls.teamInfoInClass("1",ContactlessTimer.Properties.Settings.Default.currentRaceID);
    //newlist contains list of long[] arrays
    //each array contains
    //long[0] = id1 (eg 33) 
    //long[1] = id2 (eg 34)
    //long[2] = totalLaps (eg 10)
    //long[3] = total time (eg 340000 in miliseconds)
    foreach (long[] Arr in listToReOrder)
    {
        foreach (long info in Arr)
        {
            //order
        }
    }
    return returnList;
}

List<long[]> returnList = listToReOrder.OrderByDescending(x => x[2])
                                       .ThenBy(x => x[3])
                                       .ToList();
