Does SORT tool work properly?

[PatriciaPG]

Hi everybody,

I have a question related to SORT tool. Sometimes it seems like it works properly. in ex.

However, If I have new points (on the left side) the results are completely different and chaotic. Somebody could know the reason? 

Thank you very much in advance,

looks fine.... see Peano Curve sort in
