Well, how would you propose to order the following list?

a = 1;
b = 1.0;
c = Pi;
d = N[Pi];
e = N[Pi, 100];
f = x /. First[Solve[Cos[x] == x, x, Reals]];
g = x;
h = x^2;
i = GegenbauerC[10, x];
j = WeierstrassP[1, {1, I}];
k = Plot[x^2, {x, 0, 1}];
Sort[{a, b, c, d, e, f, g, h, i, j, k}]

As you sent at least four queries from you on this topic yesterday, in
increasing order of exasperation, you might be interested in the
stackexhange proposal for a mathematica group:
