Somehow I managed to broken my installation trying to compile compiz myself at my spare computer (then I installed 12.10 and scale is working now). But at my work computer I managed to pin bruno santos ppa this way:
# echo compiz-core hold | dpkg --set-selections
# echo compiz-plugins hold | dpkg --set-selections
# echo compiz hold | dpkg --set-selections
