I got curious, so I looked a little more into this. I've attached a composition (and a video of said composition) demonstrating the (apparently more unusual than I expected) behaviour of the Sort Points by Distance node.

The composition generates a random reference point (orange) and a list of randomly generated points that gets run through the Sort Points by Distance node (blue).

The mouse's position controls how many of the blue points you'll see at once using a Cut List node. The horizontal position controls the Start Position (left is 1, right is the last list index) and the vertical position controls the Item Count (bottom is 1, top is list size).

The composition demonstrates that the Sort Points by Distance groups them into ring-shaped regions. You can experiment with different reference points by clicking the mouse. Adjusting the window regenerates all the points so they still fit inside window's constraints.

How severely does this bug affect you?: 

●●●○ — It prevents me from completing a specific task with Vuo.

Steps causing the bug to occur: 

  1. Use the Sort Points by Distance node with 2D Points

The attached composition creates a list of 10 random 2D Points and sorts them by distance to an additional random 2D Point. The list is processed and the distances calculated by a Measure Distance node (whose functionality I have verified) and the distances are printed to a console window. Sadly, they are not in order.

Have you found a workaround?:
