Sort help states "Sorting of complex entries is done first by magnitude
(‘abs (Z)’) and for any ties by phase angle (‘angle (z)’)."

That sort order should apply only for complex numbers and not for real
numbers. For matrices it should apply only to those columns or rows with
complex numbers, not those columns or rows with all real numbers. Otherwise
the presence of a complex component in row 52 causes the sort order of
all-real row 1 to change, which is a bug.
