As far as I know the 5-hole side is always the most significant 5

holes go :

Where S is the sprocket hole and a digit is the bit number (bit 0 is
the least significant bit).
As to which way use the tape, with the tape feeding towards you, the
sprocket hole is normally offset towards the right, that is the bits
would read with the MSB on the left. I am not sure if that is
universal though
FWIW, the ECMA standard is here https://www.polyomino.org.uk/computer/ECMA-10/
