Sorting table from highest to lowest?

I'm attempting to write a script where it takes the table and sorts out the lap number from highest to lowest. The thing is, it correctly prints out the first player, but the players afterwards bug out.

Table script:

local allPlayers = game.Players:GetPlayers()

table.sort(allPlayers, function(a, b)
    return a.Lap.Value > b.Lap.Value
end)

while wait(0.001) do
    for i,v in next, allPlayers do
        print(v.Name .. ": " .. i .. "th")
    end
end

PlayerInstance script:

local allPlayers = game.Players:GetPlayers()
local test = game.Players.LocalPlayer:GetFullName()

for _, player in pairs(allPlayers) do
    if player.Character then
        if  test ~= "Player.Sxerks2" then
            -- was only a test
            local lapNum = Instance.new("IntValue", game.Players.LocalPlayer)
            lapNum.Name = "Lap"
            lapNum.Value = 2
        end

        local lapNum = Instance.new("IntValue", game.Players.LocalPlayer)
        lapNum.Name = "Lap"
        lapNum.Value = 1

        local checkpoint = Instance.new("IntValue", game.Players.LocalPlayer)
        checkpoint.Name = "Checkpoint"
        checkpoint.Value = 0
    end
end

Thanks!
