How do I make this script correct and not incorrect?

So whenever it reaches a certain amount, it doesnt break like it is soupossed to.

EX: It thinks 76 isnt less than 80 and 76 isnt greater than 80

All it does is NOT doing what it needs

(also it only reaches 1 and 2, doesnt pass to 3)

Code:

for i,v in pairs(workspace.Map:GetChildren()) do
			print('1')
			if v:IsA('Part') or v:IsA('WedgePart') or v:IsA('UnionOperation') or 	v:IsA('CornerWedgePart') then
				print('2')
				if tonumber(v.Name) <= i and v:FindFirstChild('BodyVelocity') == nil then -- < MAIN PROBLEM
					print('3')
					v:BreakJoints()
					local BV = Instance.new('BodyVelocity',v)
					BV.MaxForce = Vector3.new(0,0,9e+20)
					BV.Velocity = Vector3.new(0,0,-20)
				end
			end
		end
