You need to somehow script the proper order and/or dependencies if you
are using mock.  You would also need to script something that would add
the built packages into a repo if you need to build them "staged" (that
is, you build package A and it is needed for Package B later ... you
need some kind of script to move the .rpms from A into one of your repos
and run createrepo on it before you build package B).

There are things that do staging for mock ... one is plague, the other
is koji ... I am sure there are others.

You need to use a command like this to build i686 for mock:

setarch i686 mock --statedir="{somepath}/state" --resultdir="{some path
to put built files}" -r "{some mock config file}" --arch="i686" {SRPM to
build}

Here is some example scripts that I use for building mock packages (this
is for the c5 mock we use for centos5 and is in c5 extras ... newer
versions for c6 will have different options):
