如何使用排序函数discord.py？

Question

我使用以下代码创建一个积分表：

@bot.command()
async def start(ctx):
    await ctx.send("How many total teams are there?")
    t = await get_input_of_type(int, ctx)
    embed = discord.Embed(title="**__Today's Result:__**", color=0x03f8fc)
    
    lst = []
    
    for i in range(t):
        await ctx.send(f"Enter team {i+1} name :")
        teamname = await get_input_of_type(str, ctx)
        await ctx.send("How many kills did they get?")
        firstnum = await get_input_of_type(int, ctx)
        await ctx.send("How much Position points did they score?")
        secondnum = await get_input_of_type(int, ctx)
        lst.append((teamname, firstnum, secondnum))  # append to results
        
    lstSorted = sorted(lst, key = lambda x: int(x[1]) + int(x[2]))  # sort results by kills + points
    
    for teamname, firstnum, secondnum in lstSorted:  # process embed
        embed.add_field(name=teamname, value=f'Kills: {firstnum}\nPosition Pt: {secondnum}\nTotal Pt: {firstnum+secondnum}',inline=False)

    await ctx.send(embed=embed) 

问题是代码运行良好，但我希望它根据总分按降序对结果进行排序，但这不起作用，我不知道我在这里做错了什么

另外，如果你能为我提供一些更好的可视化结果的建议，我们非常欢迎你。 谢谢
