Are you sure it isn't getting co-elleced into the same group as the 1.7.0? It could be in a popup (look to the right of the table).

This panel controls the order in which JVMs are scanned for a version that matches the JVMVersion in the Info.plist. But you should also be able to drag Java 7 to the top of that list so it can be used as the default Java for the command line.

While the OpenJDK JVMs do not offer any capability beyond CommandLine, they should always show in Java Preferences.
