Sounds like the problem would be in other parts of the logic. Is total calculated once for the whole file, and you run it again and again for each user, or how do you end up with that total?

A common technique is to keep an array of totals where the keys are the users, so you only have to run over the file once.

Code:
awk -F : '{ if (++total[$1] > 500) print $1, $2 }' file

(This will print multiple times, once for each record after the total is exceeded. Figuring out how to avoid that is left as an exercise.)

Once you get it to print what you want, just pipe that output to sort.

nologin

NOLOGIN(5)						      BSD File Formats Manual							NOLOGIN(5)

NAME

     nologin -- disallow logins

DESCRIPTION

     Programs such as login(1) disallow logins if the nologin file exists.  The programs display the contents of nologin to the user if possible
     and interrupt the login sequence.	This makes it simple to temporarily prevent incoming logins systemwide.

     To disable logins on a per-account basis, investigate nologin(8).

SECURITY

     The nologin file is ignored for user root by default.

IMPLEMENTATION NOTES

     The nologin feature is implemented through login.conf(5), which allows to change the pathname of the file and to extend the list of users
     exempt from temporary login restriction.

     PAM-aware programs can be selectively configured to respect nologin using the pam_nologin(8) module via pam.conf(5).

     The nologin file will be removed at system boot if it resides in /var/run and cleanvar_enable is set to ``YES'' in rc.conf(5), which is
     default.  Therefore system reboot can effectively re-enable logins.

FILES

     /var/run/nologin  default location of nologin
