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
