An 11 year old, actually. That's when I learned the meaning of these terms. And yes, I'm from India. :)
Power, being dW/dt is a scalar, since work is a scalar.
Also, I'd like to point out that Torque is the rotational equivalent of Force, although it's unit is of work (Joules). Angular displacement is dimensionless, so when you multiply torque with angular displacement, you get work. Torque isn't work.
It's quite logical. Consider two observers in two different reference frames. Their observations will obviously differ. Now you don't have any reason to prefer one's observations over other's. This is exactly what relativity says.
