The ordering does not matter.  GPG supports selecting a user ID by hash:

gpg --with-colons --list-keys (whatever)

....
uid:-::::2006-08-02::A8DCEA454269C4701E724839B04AEDD404BC21EB::Foo Bar <foo at example.com>:
                     ^^^^^^^^^^^^^^^^^^^^^^^^^^
                      this is the hash value


gpg --edit-key (whatever)
uid A8DCEA454269C4701E724839B04AEDD404BC21EB
