change order of nodes in subgroup in graphviz

In the following code:

digraph G { 
  splines=true;

  bpx_launch -> bpx_preproc [color=red];

  subgraph cluster_0 {
    slice01;
    slice02;
    slice03;
    slice_i;
    slice_N;
    color=black;
  }

  bpx_launch -> bpx_postproc [color=red];
  bpx_launch -> bpx_validate [color=red];
  bpx_launch -> slice01 [color=red];
  bpx_launch -> slice02 [color=red];
  bpx_launch -> slice03 [color=red];
  bpx_launch -> slice_i [color=red];
  bpx_launch -> slice_N [color=red];

  bpx_preproc -> slice01 [color=blue];
  bpx_preproc -> slice02 [color=blue];
  bpx_preproc -> slice03 [color=blue];
  bpx_preproc -> slice_i [color=blue];
  bpx_preproc -> slice_N [color=blue];

  slice01 -> bpx_postproc [color=blue];
  slice02 -> bpx_postproc [color=blue];
  slice03 -> bpx_postproc [color=blue];
  slice_i -> bpx_postproc [color=blue];
  slice_N -> bpx_postproc [color=blue];

  bpx_postproc -> bpx_validate [color=blue];
}

I end up getting slice_N, slice01, slice02, slice03, slice_i, but I would prefer slice01, slice02, slice03, slice_i, slice_N. Is there any way to change that order?

Also, how do I add a key for arrows? I would like to show a little legend which explains that "x -> y" means "x launches y" for red and "x must run before y" for blue.

EDIT: Mistakenly had the first 'bpx_launch' as 'bpx' so it didn't make sense - it should all read as 'bpx_launch' - there should be no node named 'bpx'

Currently (version 2.38) ordering other than by rankdir is not working within clusters neither by the order of appearence nor by edges.

without clusters

digraph G { 
    splines=true;

    legend [shape=plaintext label=<<table  border="0" cellborder="0"><tr><td><font color="red">- launches</font></td></tr><tr><td><font color="blue">- runs before</font></td></tr></table>> ]

    { rank=same color=black
        slice01 -> slice02 -> slice03 -> slice_i -> slice_N [style=invis]
    }

    edge [color=red]
    bpx_launch -> bpx_preproc;
    bpx_launch -> bpx_postproc;
    bpx_launch -> bpx_validate;
    bpx_launch -> slice01;
    bpx_launch -> slice02;
    bpx_launch -> slice03;
    bpx_launch -> slice_i;
    bpx_launch -> slice_N;

    edge [color=blue]
    bpx_preproc -> slice01;
    bpx_preproc -> slice02;
    bpx_preproc -> slice03;
    bpx_preproc -> slice_i;
    bpx_preproc -> slice_N;
    slice01 -> bpx_postproc;
    slice02 -> bpx_postproc;
    slice03 -> bpx_postproc;
    slice_i -> bpx_postproc;
    slice_N -> bpx_postproc;
    bpx_postproc -> bpx_validate;
}

you get
