Hi Wally. There are two things going on here. One is that Maxima
tries to arrange expressions into a so-called canonical form.
The other is that Maxima has ideas about how to display the
canonical form of an expression.

Yes, via the global flag "powerdisp".
powerdisp : false;
a + b + c;
=> c + b + a
powerdisp : true;
a + b + c;
=> a + b + c
To judge by the name, powerdisp was invented to control the
display of polynomials. But it actually affects all "+" expressions.
?? disp
finds some info about powerdisp and other display variables.
