 From what you wrote, it seems to me they want a CMYK colour profile 
embedded in the file. You can do this in scribus in the properties 
palette, provided you have such a profile. If you don't need brilliant 
colours, you can also try sRGB, which normally translates easily to 
CMYK. It's not what I would recommend generally, but just in case ...

Yes, it should ;)

In current GIMP, you can't work in the CMYK colour space, neither can 
you apply any profiles. These features will be available in the next 
version (2.4). But if you don't need to edit your file, scribus is your 
friend. You can attach a profile to the image, do the gamut check and 
let scribus do the conversion when exporting to PDF.
