cron doesn't care how many times you invoke the same script file. So why not invoke it 16 times at the time you want it to run?
0 0 * * * * /usr/bin/cleanup
30 1 * * * * /usr/bin/cleanup
0 3 * * * * /usr/bin/cleanup
.

30 22 * * * * /usr/bin/cleanup
Without doing some research, and assuming that the SCO I'm familiar with might work differently, I would suspect that the 90 minute sequence of executing might be determined by the time of the last reboot.

UUPOLL(8) System Manager's Manual UUPOLL(8)
NAME
uupoll - poll a remote UUCP site
SYNOPSIS
uupoll [ -ggrade ] [ -n ] system
DESCRIPTION
Uupoll is used to force a poll of a remote system. It queues a null job for the remote system and then invokes uucico(8).
The following options are available:
-ggrade Only send jobs of grade grade or higher on this call.
-n Queue the null job, but do not invoke uucico.
Uupoll is usually run by cron(5) or by a user who wants to hurry a job along. A typical entry in crontab could be:
0 0,8,16 * * * /usr/bin/uupoll ihnp4
0 4,12,20 * * * /usr/bin/uupoll ucbvax
This will poll ihnp4 at midnight, 0800, and 1600, and ucbvax at 0400, noon, and 2000.
If the local machine is already running uucico every hour and has a limited number of outgoing modems, a more elegant approach might be:
0 0,8,16 * * * /usr/bin/uupoll -n ihnp4
0 4,12,20 * * * /usr/bin/uupoll -n ucbvax
5 * * * * /usr/sbin/uucico -r1
This will queue null jobs for the remote sites at the top of hour; they will be processed by uucico when it runs five minutes later.
FILES
/etc/uucp/ UUCP internal files
/usr/spool/uucp/ Spool directory
SEE ALSO
uucp(1), uux(1), uucico(8)
