The selection functionality is the same in AI10 as it was in 7.  Works for me.  Once again, another explanation... 

With any other tool selected you can hold down Ctrl to get the last selection tool you used.  While holding Ctrl and hitting Tab, you can toggle between the selection tool and the Direct select tool.  If, while holding Ctrl, you have the direct Select tool, you can also hold down Alt to get the Group Select tool.  The functionality is the same as described, Each click on an object will select the items within that group in the order they were grouped. 

First, you need to see if the group select tool is woking properly, without the Ctrl Alt keys.  If that works as expected, but not the same as when you use the keys, then something is wrong.  I can tell you though, I use this feature quite often and have noticed no difference between version 7 and 10.  Unless I have missed something...
