Help reserving UID ranges?

We have recently merged 2 old systems onto a newer Itanium platform. As part of this work we merged the password files and assigned new UID's beginning from 1000. I have a user add script that admins can use to add a user, however this assigns the next available UIB (in the low 100's) rather than 1000 upwards.
Does anyone know how I can either reserve UID's 1 - 1000, or script so the useradd only adds from the next available UID above 1000?
Thanks in advance,
Tom.

PAM_ROOTOK(8)							 Linux-PAM Manual						     PAM_ROOTOK(8)

NAME
pam_rootok - Gain only root access SYNOPSIS
pam_rootok.so [debug] DESCRIPTION
pam_rootok is a PAM module that authenticates the user if their UID is 0. Applications that are created setuid-root generally retain the UID of the user but run with the authority of an enhanced effective-UID. It is the real UID that is checked. OPTIONS
debug Print debug information. MODULE TYPES PROVIDED
The auth, acct and password module types are provided. RETURN VALUES
PAM_SUCCESS The UID is 0. PAM_AUTH_ERR The UID is not 0. EXAMPLES
In the case of the su(1) application the historical usage is to permit the superuser to adopt the identity of a lesser user without the use of a password. To obtain this behavior with PAM the following pair of lines are needed for the corresponding entry in the /etc/pam.d/su configuration file: # su authentication. Root is granted access by default. auth sufficient pam_rootok.so auth required pam_unix.so SEE ALSO
su(1), pam.conf(5), pam.d(5), pam(7) AUTHOR
