I sort of solve the problem in my libray by adding a comment of Misc or Single for an album that has just one track, then do a smart playlist with that criteria Comments = Misc.
Other than that I would think its impossible without a script.
Apple definitely need to introduce some album specific criteria in the next release of iTunes
i.e
"Album length" =, >, < 30 minutes
"Album contains" = < > 5 Tracks
"Album Genre" is NOT Rock
"Album Year"
