A question I would ask first is: Why PDF/X-3 if you want to print greyscale or

For converting colour pictures to real greyscale in GIMP, please read the 
tutorial here: http://www.gimpguru.org/Tutorials/Color2BW/

This seems to make sense, since your printer probably only needs to produce 
two plates instead of four.

You can do yourself a favour and wait a few days until Scribus 1.3.3 is 
released. It has additional greyscale export, as long as you don't use

I had no chance to test greyscale export of 1.3.3, but if you need high 
quality greyscale files, I'd follow the instructions for creating greyscale 
images in the tutorial mentioned above.

As above: Even if you don't trust 1.3.3 yet, install it in addition to your and try the greyscale option in PDF export.
