Yes, this is frustrating.  I've encountered it a number of times while
packaging perl modules that override those in the core (e.g.
Test::More).  Sorry, but I've never found a really good solution beyond
--force or --replacefiles.

Thinking this through from the rpmdb's perspective, which of the two
packages 'owns' the man pages.  If you were to, say,

	rpm -e perl.i386

would you expect it to remove the man pages or not.  What would you expect

	rpm -V perl

to report in either case.  As far as I'm aware there is no such
'duplication' logic in the db. It would be cool if it could be made to
work in general, however, I can think of some use cases that might rule
this out.  By using --force (or --replacefiles) you are effectively
breaking the consistency of the install/upgrade/remove logic and yum
should protect you from doing that by accident.

Stepping back a bit, why do you need both perl.i386 and perl.x86_64
packages?  Which package 'owns' the /usr/bin/perl executable?
None of my Centos 5 x86_64 systems have both and they have all gone
through a recent perl upgrade, so I'm curious how you got both installed
in the first place.  Is there some dependency that pulled in the i386
package?
