Are you having a problem with your SMTP server not delivering to the
correct mailbox? Or are you retrieving the attribute to display is some
application?

I am not aware of a way to order attributes or values.

An alternative approach that I've used, where I may have multiple mailDrop
attributes for an alias (or may not have any aliases at all for a given
mailbox) but want to return one consistent primary entry to our spam
filtering device, is to populate another, unique, attribute solely for the
purpose of returning a consistent value to that particular application, and
is unused by our SMTP server.
