Part of the original scheme was that you can say:
cron -> is a 'bo' package
libc6 -> is a 'hamm' package
cvs -> is a 'hamm' package
all others are default (bo). If a new version of cron was added to the bo
package file then it would be marked by the UI for auto upgrade, if a new
version of cron was added to the hamm package file then nothing would
happen.

The order is to choose a source for the upgrade. IE if you a CD and a FTP
mirror setup as sources then you will want as many packages as possible
(iff they are the newest versions) to come off the CD. So by listing the
CD first it will take priority for same version conflicts. Any distinct
versions will be listed twice and then the UI will pick the higher one.

One equal version. Ie there may only be one 2.3 in the list, but there can
be a 2.2, 2.4 also. The one that is put in the list is the first one
found.
