Re: Proposal: add a sale (and discount) property to Offer

Quickly: I am not a big fan of this direction. For discounts, simply use the advanced price modeling with UnitPriceSpecification.
Conceptually, a discounted offer is nothing but an offer.

See 

    http://wiki.goodrelations-vocabulary.org/Cookbook/Pricing

for examples of what can already been done with the existing GoodRelations elements in schema.org.

Note the slight naming differences, explained in

There are places where it becomes problematic (e.g. conflicting types), but I believe it scales better (e.g. when it is discovered that a DiscountOffer have more specific discount-related properties, such as discount amount, etc.).
