Actually, the problem is that your sort function is invalid, it doesn't
follow the correct contract:
He stated quite clearly in his original post that he's aware that his
sort function is invalid. His question was why does Lua call the
function with nil values, when it has a nice error message "invalid
order function for sorting", that apparently due to a bug it does not
use. Such a message would be very useful in more complicated sort
functions with larger tables, as such an abstract nil error message
might take forever to find the cause of. If it won't damage
performance, that is definitely a bug in Lua that should be fixed.
