you should not use that: switching to Gtk2::UIManager usually solves
most issues, and UIManager is at least actively maintained - while
ItemFactory is deprecated.

get the MenuItem widget from the ItemFactory using its path and then set
it to be active:

  $factory->get_item('/Frontend/scan_image')->set_active(TRUE);

Using Gtk2::UIManager would make this a bit simpler: just set the value
of the active RadioAction when adding the actions to the ActionGroup:

  use constant {
    SCAN_IMAGE => 0,
    SCAN_ADF   => 1,
  };

  my @radio_actions = (
    [ 'ScanImage', undef, 'Scan Image', undef, undef, SCAN_IMAGE, ],
    [ 'ScanAdf',   undef, 'Scan Adf',   undef, undef, SCAN_ADF,   ],
  )
  my $radio_actions_ref = \ radio_actions;
  my $on_change_ref = \&on_change;

  # set the the action wit value 'SCAN_ADF' as the default
  $action_group->add_radio_actions($radio_actions_ref, SCAN_ADF, $on_change_ref);

ciao,
 Emmanuele.
