I don't have 10.6, but 1.7.0 JVMs show up in Java Preferences in 10.7. It could be that, but I don't think so. Mike can confirm.

I thought this was because Java 7 can't be used for bundled Java apps that use JavaApplicationStub. 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.
