Have a look at
http://article.gmane.org/gmane.comp.web.eprints.devel/9278
n.b.: this only affects views, not the divisions or subjects tree in
Edit (don't know how to do that)!

You don't have to change "sub get_children" in
/opt/eprints3/perl_lib/EPrints/DataObj/Subject.pm, you can overwrite
this method only for one certain archive in e.g.
/opt/eprints3/archives/<archiveid>/cfg/cfg.d/zzz_local.pl , like this:

sub EPrints::DataObj::Subject::get_children {
  my( $self ) =  AT _;
  if( $self->{session}->{subjects_cached} )
  {
    my $subjectid = $self->get_value( "subjectid" );
    return  AT {$self->{session}->{subject_child_map}->{$subjectid}};
  }
  my $searchexp = EPrints::Search->new(
    session=>$self->{session},
    dataset=>$self->{dataset},
    custom_order=>"subjectid" );
  $searchexp->add_field(
    $self->{dataset}->get_field( "parents" ),
    $self->get_value( "subjectid" ) );
  my $searchid = $searchexp->perform_search();
  my  AT children = $searchexp->get_records();
  $searchexp->dispose();
  return(  AT children );
}

Don't know if this is ok, but for me it works.
