Would scale counts work between different sub-species? And what are the expected count for each sub species? If you are going to do a scale count do it on a shed skin pined to a board. Count arount the mid body of the skin from belly scale to belly scale an count along the diagonal.
Here is a diagram which I hope shows how to count scales. count along the Xes.

And you have a cute little snake there but I am not game to venture an opinion as to which sub-species it is ( its not a water python or a olive python, if that helps
). I think you will need to wait until the snake is much older.
