You can only group calendars under the heading "On My Mac" in the Calendars list.
If you are using iCloud, you may not see the "On My Mac" heading unless your temporarily disenable (uncheck) your iCloud account in Calendar>Preferences...>Accounts.OS X Mountain Lion (10.8.3), iPad 3G, iPhone 4, 20GB iPod Color, iPod shuffle
I am not using iCloud and unfortunately when I clicked the iCloud option (it was unchecked under Calendar>Preferences ), it wiped out my entire calendar.
I still can't add a "Calendar Group" option.
