First, the stamps aren't in the Scott catalog.
Second, I don't have any information about the "PAID" overprint, however, I can only assume it was a way to cancel the stamps to show that the value of them were "PAID" out.
However, for information on the stamps in general, this article may help explain it. It was the early rendition of Food Stamps (or SNAP Program) as we know it today.

Quote:
The plan provides the grant by the Government of $1.50 in food orders to the beneficiaries for each dollar of the WPA wages or dole money they expend. For each cash dollar, an unemployed person would get $1 in orange stamps and 50 cents in blue stamps.
Orange stamps are good for any grocery item the purchaser elects, except drugs, liquor, and items consumed on the premises. Blue stamps, however, will buy only surplus foods -- dairy products, eggs, citrus fruits, prunes, fresh vegetables, and the like.
