I used the following code to get the ID's of the menu items:
        ...

        filerecentmenu =3D wx.Menu()
        filemenu.AppendMenu(wx.NewId(), "&Recent Files", filerecentmenu)
        self.hist.UseMenu(filerecentmenu)
        self.hist.AddFilesToMenu()
        ...
        for item in filerecentmenu.GetMenuItems():
            print item.GetId()

For some reason, wx.ID_FILE1 is not the ID of the first item in the recent
files menu. There are two items in the recent files menu, and their ID's are
102 and 103. wx.ID_FILE1 and wx.ID_FILE2, on the other hand, are 5050 and
5051, respectively. This would explain why the EVT_MENU_RANGE is not binding
to the correct items.

The good news is that if I explicitly use 102 and 103 as id and id2 for the
EVT_MENU_RANGE, everything works as expected - the recent files open . But I
just did it for testing purposes.

Is there any way I can get the recent file MenuItems to have wx.ID_FILE1 and
wx.ID_FILE2 as their IDs. without explicitly defining the IDs? Now that I
have identified the exact nature of the problem, finding a solution should
be easier.
