I've modified slightly your code to use it with an Attiny85, only one motor, but for some reason, the motor only spins in one direction. In fact I've checked that during the inversion period the motor doensn't move. I've changed the order of activation MotorA1, MotorA2, HIGH and LOW and nothing happens. I don't think the problem is the Attiny85.

Pin 1 and pin 9, for being able to drive the motor, the pin 1 and 9 need to be high. For driving the motor with left H-bridge you need to enable pin 1 to high. And for right H-Bridge you need to make the pin 9 to high. If anyone of the either pin1 or pin9 goes low then the motor in the corresponding section will suspend working.
What is VCC in motors?
VCC is the voltage that it needs for its own internal operation 5v; L293D will not use this voltage for driving the motor. For driving the motors it has a separate provision to provide motor supply VSS (V supply). L293d will use this to drive the motor.
