There can be a lot of processes named cron. You are picking one at random and attempting to see if it's your parent. In your crontab entry do something that you won't do interactively. Like:
55 18 * * * /path/to/script runfromcron
Then just check $1.
This faster, easier, and you have a way to more easily test the script's operation.
I'm puzzled by this one. I hope you can explain it to me.

yum-cron
yum-cron(8)yum-cron(8)NAME
yum-cron - an interface to convieniently call yum from cron
SYNOPSIS
yum-cron [config-file]
DESCRIPTION
yum-cron is an alternate interface to yum that is optimised to be convenient to call from cron. It provides methods to keep repository
metadata up to date, and to check for, download, and apply updates. Rather than accepting many different command line arguments, the dif-
ferent functions of yum-cron can be accessed through config files.
config-file is used to optionally specify the path to the configuration file to use. If it is not given, the default configuration file
will be used. It is useful to be able to specify different configuration files for different use cases. For example, one configuration
file might be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file.
Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day.
FILES
/etc/yum/yum-cron.conf
/etc/yum/yum-cron-hourly.conf

the mailing list, yum@lists.baseurl.org, or consult bugzilla.
