ISO 50 is just overexposed ISO 100. It is useful for lower contrast subjects as you get a bit more exposure in the shadows. But shooting ISO 100 with +1EV exposure comp will yield the same file.

Yes, except that they are displayed and converted (by default) differently by SPP. The JPEG, the LCD and also standard SPP conversion, will render the ISO 50 image darker than the +1 compensated image. But, the RAW data will be the same.

ArvoJ wrote a little utility that you can use to change the iso tag in the raw file.  It can be found here.

It works well and I had some fun playing with it.
