Virginiarose, my plant (that I think is 'Arizona Apricot') does have shorter flower scapes than the other one - but they were raised in different environments so I don't know that I can count on that being true next year. Also, the blooms on my AA also seem to have a single row of petals, as does the O&L.
For what it it worth, though, I am letting some seed heads develop on each plant. Thus far, the ones on AA look like a golden yellow, whereas the one or two on O&L look more like a chartreuse lemon, which is hopefully another confirmation of the identity.
