Two years ago I had quite many softnecks producing real scapes. Usually there has been bulbils growing inside the stem, but that time the scapes were like with hardnecks. The ones with scapes had smaller bulbs than the ones without. I planted cloves from the bulbs with the real scape, but they did not grow scape like that the next year.
Here is the thread about the thing:
