Check the listings on the sites below to see if they might have what you're looking for. Individual cultivars are grown and rotated on about a three to four year basis so if you don't see what you're looking for this year, then it may show up next year or the year after.
If you only cut the top one third of the bulb off, then it should survive because the central core deep within the bulb will still be untouched. It will shoot up a much smaller and spindlier stem next year, of course. If any buds form, you should disbud them. You could try to make some scale bulblets from some of the larger severed scales but don't hold out too much hope for success because the cut as you describe it is too far away from the basil plate and most would likely be too small. You didn't say how large the bulb was, but given the same circumstance, I'm inclined to agree with Joe and I would have taken at least three scales for cloning, especially if it was one of my favorites. Again, I'm almost certain your bulb will survive. Make sure you mark the spot where you planted it well because it may emerge later next Spring or, in a more rare instance, it may wait until the following year to come up.
Here's the list I mentioned.
