It works, if I provide a normal function or a string lambda as 
'less'. However the code above results in the following error:

/d923/f233.d(11): Error: constructor 
f233.__unittestL15_3.Set!((x, y) => x < y, 
int).Set.__ctor!(int[]).this cannot get frame pointer to sort

What's wrong?

This looks like a bug to me, seeing as string predicate works. Although I don't get how you supply default template parameter for Set before explicit one :)
