This is exactly what construction-variable overrides are for.

 png19 = env.MakeGraph(tgt, sources, SLICE=19)

Then in your python action, just look at env['SLICE'].

You're not abusing SCons at all, the above is perfectly normal.  (But
as Dmitry says, you may care about regenerating png19 if you change
the slice, in which case you could use a Value node, or even have an
emitter that adds a dependency on an internal Value node.)
