Native android tab group is ALWAYS forced to the bottom by the OS (not by appcelerator). The following post explain how to achieve Bottom tabbar in Titanium(Android OS)
The first thing you want to remember is 90% of whatever you want to be changed using any native config, can be done in Ti by placing that file in the projects root, under whatever structer it was to have in native land. So if the file in a native app would be in '/foo/text.xml', in Ti you would place it in '%your apps project root%/foo/text.xml' Knowing that will help you with a lot of more advanced topics in Titanium dev.
Create a new project, and add the following xml into a file named 'titanium_tabgroup.xml' (without the quotes), inside a new project directory you will create called '%your apps project root%/platform/android/res/layout/' (again, without the quotes).
The XML you want to add is found in this gist
Then do a clean build of your app and run in android :)
Sample Output from Android Simulator
Here you can download the complete working project from my Github Android Bottom Tab Group
