Increasing coeffs flag is for symbolic output only. 1-d polynomial input/output as a list of coefficients is sorted from x^n to x^0.

Thank you. But how does SORT work on a list that has both real and complex numbers? It does sort the real numbers from small to large, but I cannot figure out what it does to the complex ones:
SORT([1 i -i 3 2+i])=[1 3 2+i i -i]
Or what it does to lists with just complex numbers
SORT([-2+i -i 2+i 3-i 5i]) = [5i 3-i 2i -2i -i]
