According to the wiki, it seems like editing the file:

/etc/yum/pluginconf.d/protectbase.conf

And adding (or changing) it to have enabled set to zero:

[main]
enabled = 0

Would disable the protectbase plugin.  Is this a valid way of disabling 
yum-protectbase in preference for yum-priorities?

For my system, I did the following to fix the issue:

A) Make sure that [extras], [base], and [upgrades] were all at the same 
priority level (I used priority=1 for all three of those sections)

B) Disabled yum-protectbase as shown above (putting enabled=0 in the 
[main] section) in the protectbase.conf file under /etc/yum/pluginconf.d/

C) Ran the upgrade command for just perl:

yum --disablerepo=\* --enablerepo=updates --enablerepo=base
  --enablerepo=extras upgrade perl

...

Many thanks to Gregory for pointing out a good fix for this issue.  I 
suspect it all goes back to having [extras] at a different priority 
level then [base] and [upgrades].
