If you want to make sure that checks run at a given time and in
sequence, I recommend you configure them as a passive checks.  Run the
checks it in a script under cron with sleeps seperating each one and
have them push the check results to nagios either by writing to the
command file or using nsca (depending on whether you run the checks on
the local or remote host).

See http://nagios.sourceforge.net/docs/3_0/passivechecks.html
