Why does this money/remove script only work half of the time?

So I have created a balloon with a humanoid in it. The head is a balloon mesh and I shrunk all the other body parts inside the mesh. Below is 2 different scripts. The first one gives the player points if they pop the balloon and the other plays a pop sound and then removes the balloon all together. If I walk up to the balloon with a sword and pop it everything works great (Balloon gets popped and player receives points), but when I use a gun from a distance and kill the balloon it will delay about 4 seconds before popping and the player doesn't receive any points. Any idea on why this is happening?

StatName = "Points"

IncreaseValue = 20



local Humanoid = script.Parent.Humanoid
function PwntX_X()
    local tag = Humanoid:findFirstChild("creator")
    if tag ~= nil then
        if tag.Value ~= nil then
            local Leaderstats = tag.Value:findFirstChild("leaderstats")
            if Leaderstats ~= nil then
                Leaderstats[StatName].Value = Leaderstats[StatName].Value + IncreaseValue
                wait(0.1)
                script:remove()
                end
                end
                end
                end
                Humanoid.Died:connect(PwntX_X)

                --- next script
while true do
    wait(.01)
    if script.Parent.Humanoid.Health<1 then
        wait(.01)
        script.Parent.Sound:Play()
        script.Parent:remove()
    end
end
