How can I order bricks?

Say I have 20 bricks lined up, and I'd want to assign them ascending numbers from one end to the other. (So the first brick would have 1, second brick would have 2, etc.)

I could always manually assign a number value by inserting a numbervalue to each brick and ordering them from 1 to 20, though that would take a bit of time.

Another idea I had was to use

for i,v in pairs (model:GetChildren()) do
local number = Instance.new("NumberValue", game.Workspace)
number.Parent = v
end

But I'm not sure if that would correctly assign the numbers in ascending order from right to left like I need. Any ideas?
