Is does not matter.

The Driverstation assigns joysticks not by where they are plugged in, but by the USB hardware ID. This is an ID similar to a mac address for a network card - it's internal to the joystick and unchangeable by you. Thus, once you plug in all your joysticks, reassign their numbers in the setup tab to get them working the way you want them to. Then use a sharpie or something else to label the joysticks so you know which one is which - because they'll stay that way from now on when you plug them in (as long as the driverstation stays configured).
