There is no such thing as bit-order.
Yes, there is. You need to read the article at
http://www.linuxjournal.com/article/6788. Explains what it means for
bits to be in one order versus another. This is from the perspective
of external devices, not the CPU (which is always consistent with
regards to bit order)

Have you ever seen a device or platform with the bits reversed?

I think when the PowerPC is running in little-endian mode, that might be the case. It needs to be able to write a byte in big-endian mode, and then read that byte back in little-endian mode and have it be the same byte.
