These are claimed to be firm, signed, definite sales, and Airbus has claimed to have taken a down payment on each of those airplanes. However, the amount of any such down payment is not public, and it's entirely possible, especially from all the hopeful startups (some of which don't yet even have an operating certificate), that the deposit in some cases was 1 Euro or some other token amount. Airbus has long said (and I agree) that deliveries, not even firm orders, is what counts, since some portion of even firm orders always get cancelled, and that portion is higher with startups that have yet even to start operating.
I believe that there is a definition of "order" under which Airbus sold 1,111 airplanes in 2005, and I believe that there is a definition of "order" under which Boeing sold 1,002 airplanes in 2005. I can't say for sure, but prior history leads me to speculate that the problem is those definitions may not be the same.
An analyst could probably sort at least some of this out, unless some of the contracts are secret.
Another consideration barely touched on is that Airbus may be outselling Boeing with some of its older models, but Boeing is doing better with models that will be sold in the future.
Finally, Airbus has a political advantage, selling to the countries in its own consortium, countries who don't dare offend the French, and countries who hate or envy the U.S.
