I have experienced two cases where aptitude returns a 0 exit status code, even if it prints error messages to the terminal:

Case 1: A package cannot be installed due to unmet dependencies.
Example: (installing something that depends on sun-java on a host with the "partner" repository disabled)

 The following packages are BROKEN:
   hadoop-0.20
 The following NEW packages will be installed:
   hadoop-0.20-native{a} liblzo2-2{a}
 0 packages upgraded, 3 newly installed, 0 to remove and 0 not upgraded.
 Need to get 41.2MB of archives. After unpacking 92.3MB will be used.
 The following packages have unmet dependencies:
   hadoop-0.20: Depends: sun-java6-jre which is a virtual package.
                Depends: sun-java6-bin which is a virtual package.
 The following actions will resolve these dependencies:

 Keep the following packages at their current version:
 hadoop-0.20 [Not Installed]
 hadoop-0.20-native [Not Installed]
