This is the order I set them in and it works fine.
TIFFSetField(ti->tiff, TIFFTAG_IMAGEWIDTH, (uint32)driver->width); TIFFSetField(ti->tiff, TIFFTAG_IMAGELENGTH, (uint32)driver->height);
TIFFSetField(ti->tiff, TIFFTAG_XRESOLUTION, (float)driver->wres);
TIFFSetField(ti->tiff, TIFFTAG_YRESOLUTION, (float)driver->hres);
TIFFSetField(ti->tiff, TIFFTAG_COMPRESSION, compression);
TIFFSetField(ti->tiff, TIFFTAG_ORIENTATION, ORIENTATION_TOPLEFT);
TIFFSetField(ti->tiff, TIFFTAG_MINSAMPLEVALUE, (short)0);
TIFFSetField(ti->tiff, TIFFTAG_MAXSAMPLEVALUE, (short) 255);
TIFFSetField(ti->tiff, TIFFTAG_PLANARCONFIG, PLANARCONFIG_CONTIG);
TIFFSetField(ti->tiff, TIFFTAG_ROWSPERSTRIP, 1L);
TIFFSetField(ti->tiff, TIFFTAG_BITSPERSAMPLE, 8);
TIFFSetField(ti->tiff, TIFFTAG_IMAGEDESCRIPTION, driver->ssjob->name);
TIFFSetField(ti->tiff, TIFFTAG_DOCUMENTNAME, driver->ssjob->name);
TIFFSetField(ti->tiff, TIFFTAG_ARTIST, progname);
TIFFSetField(ti->tiff, TIFFTAG_SAMPLESPERPIXEL, 3);
TIFFSetField(ti->tiff, TIFFTAG_PHOTOMETRIC, PHOTOMETRIC_RGB);

Gute Idee, Herr Wiesenfarth. Danke.
However, I forgot to mention that I already tried setting the fields in various different orders, and nothing seemed to help.

When I write an RGB TIFF using the following code, BitsPerSample in the resulting file is always 0,0,0. I must be missing something. Does anyone see my problem?

Maybe you have to set SamplesPerPixel _before_ setting BitsPerSample?
Just a guess...
