TTBOMK, new binary packages should not affect the ordering of the
package in the build queue.  The sort criteria are, in order of
precedence: the upload target; out-of-date vs. uncompiled; the source
package priority; and the source package section.  If you want to know 
the ordering of the sections, though, other than looking at 
http://buildd.debian.org/stats/ you probably need to read the code.

In addition to the overall package ordering, individual buildds can opt
out of building a particular package by putting it in weak-no-auto, if
there's a particular reason that buildd can't build it successfully or
if it's not an efficient use of resources for the buildd to do so.

Which architecture are you seeing this problem on?
