IMHO, Fresher milk is better.
Milk, even pasteurized, changes over time. The constituent components of milk seem to always be doing stuff. The lactose, fats, proteins etc.
I doubt, however, you will be at any elevated risk to mold than had you used fresh milk, but the milk/cheese may not behave the same way with old milk, if only at a microscopic level.
You run the risk of having the older milk affect the texture, taste, or smell of the final product.
But hell, rather than throw it away, make the cheese anyway. It'll prolly be edible!
