Before you say there is no such thing as a clipping path in a TIFF file, you better try importing TIFF's (with clipping path) produced by PhotoShop into PageMaker.
I believe all of Adobe's apps use a common format for their proprietary junk (including clipping paths) that they stuff into a number of different image file formats. In TIFF this block is in a private tag (34377 sounds right). In JPEG they put the same data into APP13 markers. Etc.
You can find specs for their data block in the Photoshop SDK documents, which were available free from www.adobe.com last I looked. The specs are fairly sketchy however, and may not give you everything you need to know if you are trying to decode the clipping path.
Tom is right, adobe specs is not clear but I've already done the job to read/write clipping paths from IRB, I'll forward you the code if you are interested.
