If your .csv file matches a particular .dlabel.nii file, what you could do is use -cifti-parcellate to generate a template parcellated cifti file, and then use -cifti-convert -from-text to put the data into that format (you will need to strip off the labels first, leaving only the numbers, after ensuring that the areas are in the same order as the parcellated file). This will allow easy display of the data on the surface. Foci files are not meant to contain data values, they are mostly just points in space.
If you have another purpose besides display, then I'd need more details before being able to say whether there is a better way to store it.
