Align ActionBar Navigation Tab icons above the tab text?

Question

The app has an ActionBar, and the ActionBar has Navigation Tabs, each containing text. I need to add icons to the tabs, in addition to the text.

I have added the icons using ActionBar.Tab.setIcon(drawable) successfully, but the icon shows to the left of the tab text.

How do I move the tab icon so it is ABOVE the navigation tab text?

(I'm using ActionBarSherlock, but figure the solution to this will work across native and ABS implementations)

You can set a custom view to each tab.

public class PropositionListActivity extends SherlockActivity implements ActionBar.TabListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState); 

        setContentView(R.layout.proposition_list);

        getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

        createTab(R.layout.tab_to_opine, R.id.tab_to_opine_title, "Vou Opinar");
        createTab(R.layout.tab_opined, R.id.tab_opined_title, "Já Opinei");
        createTab(R.layout.tab_feedback, R.id.tab_feedback_title, "Feedback");
    }

    public void createTab(int view, int titleView, String title) {
        ActionBar.Tab tab = getSupportActionBar().newTab();
        tab.setTabListener(this);
        tab.setCustomView(view);
        getSupportActionBar().addTab(tab);

        ((TextView) findViewById(titleView)).setText(title);
    }
}

tab_to_opine.xml
