They Loft better when sorted, eh? 
But I see two areas that look ugly (twisted), even with âAlign sectionsâ enabled. Still needs work?
To get a clean Loft, I added an Anemone loop (white group) after sorting them in sequence. It flips each curve and adjusts its Seam (start/end point) to match its predecessor. No Loft options required.

P.S. This is what Loft produces at three stages of the model. Left to right, below:
- raw curves, unsorted
- curves sorted by Z value of Avr points
- sorted curves after Anemone with matching directions and seams
