However, since the colours aren't stored as spot colours, they end up being imported as something like "FromPDF#00000040", which is completely useless when referring to a printed colour swatch that is based on CMYK ink mixtures.

The question is, what are you doing with the numbers? It seems that
Scribus stores CMYK in hex values, even though when you create them you
are shown a percentage scale.

But 40/255 ≠ 25%  (more like 16%).
