I rarely bother with numbering the cables as they're being pulled. As others have said, I'm going to test each cable anyways, so I tone, test and label then.

What I have noticed with some people who do label the cables when they pull them, is they try to terminate them "in order" at the patch panel. You can either dress the cables out neatly, or you can fight with them to put them in order. Does it matter if two adjacent offices have cables run to two adjacent patch panel ports? Personally, I don't think so.
