How do I rotate a welded item on my torso?

script.Parent.Touched:Connect(function(hit)
	local humanoid = hit.Parent:FindFirstChild("Humanoid")
	local playerName = hit.Parent.Name
	if humanoid then
		print(playerName.." is cool!")
		local torso = hit.Parent.Torso
	local weld = Instance.new("Weld")
	script.Parent.CFrame = torso.CFrame * CFrame.new(0, 0, 1, 90, 0, 0)
	weld.Part0 = torso
	weld.C0 = torso.CFrame:Inverse()
	weld.Part1 = script.Parent
	weld.C1 = script.Parent.CFrame:Inverse()
	weld.Parent = script.Parent
		script.Parent.Anchored = false
	end
	
end)

I understand how to do the position but for me, the thing I got confused on was the rotation of it. I attempted to add 3 numbers on to it for a rotation as I would in HTML but that didn't have any results.

instead of using Welds use WeldConstraints so the joint doesnt break when you try to rotate the connected parts. use CFrame.Angles() to rotate the part. also this would only work for R6 since R15 and rthro dont have torsos, instead you could use the HumanoidRootPart which is available on all avatars.

script.Parent.Touched:Connect(function(hit)
    local humanoid = hit.Parent:FindFirstChild("Humanoid")
    local playerName = hit.Parent.Name

    if humanoid then
        print(playerName.." is cool!")
        local torso = hit.Parent.HumanoidRootPart
    	local weld = Instance.new("WeldConstraint")

    	script.Parent.CFrame = torso.CFrame * CFrame.Angles(0,math.rad(90),0) -- rotates it by 90° 
	weld.Part0 = torso
	weld.Part1 = script.Parent
	weld.Parent = script.Parent
	script.Parent.Anchored = false
    end
end)
