I've just learned the way which is used to activate the console in version 1.3:
"Go to My Documents\My Games\Heroes of Might and Magic V\Profiles* and then the profile I want to apply it to. Open the 'input.cfg' in NotePad, and add the line
bind show_console '`'
just beneath the
bind confirm_action 'NUM_ENTER'

So far I haven't tested the cheats extensively, but at least the movement points cheat still works perfectly.
I guess the actual commands still work the way they did in version 1.2, it's just that one more file needs to be edited to activate the console.
