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.

Works fine for me at 10.6. Both java_home and Java Preferences.

Tried each location I know of for a second 1.7.0 install
/Library/Java/JavaVirtualMachines
/System/Library/Java/JavaVirtualMacines
~/Library/Java/JavaVirtualMachines

No problems in displaying that I noticed from any location.
