Importing Multiple Files Changes Import Order

I'm trying to import three files that are actually dumps from the three OUs in our Active Directory system to be able to maintain a valid list of users and email addresses. Unfortunately, all three OUs have different sets of information in them and therefore require different import orders for each.

So if I run the script that runs the first import, everything works fine. If I run the second one, it breaks the preset sort order set in the script. If I go back and look at it, the sort order is all messed up.

If I run the second and third sripts, the first one's order is then messed up, as well. I can't figure out what I'm doing wrong!

Any help is greatly appreciated.
