Thanks, Karl-Dieter.
I've made a little more progress:
1. Supports solutions now, including different instances of same problem.
2. No more \begin{sageprocesstext}{Problem}, just \begin{sagetext} now;
less clutter.
3. It's a single \include that you put right after \begin{document}, but
you still have to make the change to sagetex.sty.
I don't think I'm ready to submit a pull request until I know what I'm
doing better. I think I'll email Dan and we can discuss this offline. I
also don't feel the need to try to pressure him to add stuff to SageTeX
just for my pet project...it's up to him. I'll post here if he and I get
any important hurdles cleared.
I'll attach the files as they currently stand, in case you want to play
with this at all. It's been...extremely minimally tested. But there is a
working example! That's all anyone needs, right? :)

% Include this file in any document that wishes to use Sage to create exams.
% Then define problems like this:
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% \begin{sagetext}
% Problem type name
%
% initialization code
%
% Text of problem
%
% Text of solution
% \end{sagetext}
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% Example:
%
% \begin{sagetext}
% Simple addition
%
% a = randint(1,10)
% b = randint(1,10)
%
% What is the sum of $\sage{a}$ and $\sage{b}$?
%
% $\sage{a+b}$
% \end{sagetext}
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
% Then to insert a problem, use \insertproblem{type name}, or \insertproblem[instance name]{type name}.
% Then to insert a solution, use \insertsolution (which inserts the next solution in the order in which the
% problems were defined) or \insertsolution[instance name] (to insert the solution that goes with a problem
% to which you've given a particular name).
%
% Examples:
%
% Problem 1: \insertproblem{Simple addition}
% Problem 2: \insertproblem{Simple addition}
% Answer 1: \insertsolution
% Answer 2: \insertsolution
%
% or
%
% Problem 1: \insertproblem[one]{Simple addition}
% Problem 2: \insertproblem[two]{Simple addition}
% The second problem's answer is \insertsolution[two], but the first's is \insertsolution[one].
