Psychometric scale with items in sets where responses imply a rank order of items
Okay. I think I finally get what you are saying. You have constructed a form of partially ipsative or forced choice scale. 

In my words, I would say that you have 100 items in total. The 100 items are grouped into sets of 4 items, and you have 25 sets. Each item is rated on a 0 to 6 scale, and within each set participants need to give different responses for each item in the set. They must give a 0 and a 6. 

This is a variant on the idea of rank ordering the items in a set. However, you would also get a little bit of additional individual difference information because participants are not just ranking items.

For further discussion, definitions, and a critique of ipsative tests see Johnson, Wood, and Blinkhorn (1988).
