Patons has many weights of Tweed wool, so look through the Paton link and see if you can find the specific wool you are looking for and have an answer that way.
Patons Ritz yarn was a bulky yarn. It was about 12 ply.http://www.ravelry.com/yarns/library/patons-ritz
It appears by looking at the Patons link I attached, that this yarn is still available. If you don't know where to find it in your area, contact Patons and they would be able to direct you to an online or retail store in your area. (at the top of the page of the Patons link, is a Store Locator tab that you could also click on).

I searched and was unable to find Patons Camelot Wool. The best I can figure out is that you might be referring to Patons Kroy Socks FX in Camelot color. So, going by that thought, it would be a sock-weight yarn; or category 1 fingering weight yarn. Therefore having a ply of 4. If I've totally misunderstood what yarn you're asking about, I've attached some URLs which might help you to translate the information you have on the yarnband into ply.
There are two meanings for 'ply' with wool. Some wool manufacturers use the term ply to describe the weight of the wool. A 2 ply is a very fine baby wool whereas a 16 ply is a chunky or heavy weight yarn. The other meaning is the number of threads the yarn consists of. For example to a hand spinner a 2 ply means a yarn that has two single threads 'plied' together to form one length of yarn.
I have 16 balls of Azalea patonised knitting and crochet wool here and when I untwist it it becomes 2 strands....which in reading some of the other things about wool its actually 4 ply....now I am looking for a fairly plain simple knitting pattern to use it on.
This does not seem to be a current yarn. I suggest you contact Paton's via their website.
