How could that work?  Cron does not use the lock files at all, it can't
serialize anything.. I'm sure hourly and daily yum-cron jobs have already
competed for the yum.pid lock. OTOH, random sleep should help a lot there.

Yes, there should be few retries, say 1 minute apart, to reduce the number
of lock failures.
