Awk help

Posting this for a friend:

I'm having a tough time coming up with an awk command for the following question:

Using the /etc/passwd file, what command will create a list of all usernames and user id numbers of all users who have accounts on the system, sorted by user id number?

The format of the passwd file is as follows:
usrid879:x:1382:1000:Student - John Q Public - 06M8W1_ZF_423_M40,,,:/home/usrid879:/usr/bin/ksh

I need to create a listing that looks like this:
John Q Public usrid879

The only problem I'm having is switching between the ':' and 'space' delimiters. Any help would be much appreciated.

NAME
pwconv - installs and updates /etc/shadow with information from /etc/passwd SYNOPSIS
pwconv DESCRIPTION
The pwconv command creates and updates /etc/shadow with information from /etc/passwd. pwconv relies on a special value of 'x' in the password field of /etc/passwd. This value of 'x' indicates that the password for the user is already in /etc/shadow and should not be modified. If the /etc/shadow file does not exist, this command will create /etc/shadow with information from /etc/passwd. The command populates /etc/shadow with the user's login name, password, and password aging information. If password aging information does not exist in /etc/passwd for a given user, none will be added to /etc/shadow. However, the last changed information will always be updated. If the /etc/shadow file does exist, the following tasks will be performed: Entries that are in the /etc/passwd file and not in the /etc/shadow file will be added to the /etc/shadow file. Entries that are in the /etc/shadow file and not in the /etc/passwd file will be removed from /etc/shadow. Password attributes (for example, password and aging information) that exist in an /etc/passwd entry will be moved to the correspond- ing entry in /etc/shadow. The pwconv command can only be used by the super-user. FILES
/etc/opasswd /etc/oshadow /etc/passwd /etc/shadow ATTRIBUTES
