scoring-project.lisp difficulty jump

[brubsby]

My complaint is that when going through the koans in order of their appearance on the meditate-linux.sh script, scoring-project.lisp kind of comes out of left field in open endedness and complexity. And the bundled solution uses lots of forms that the user is not previously familiar with: '(sort copy-list search remove). It seems like this lesson should come later, or have some more koans with these keywords come beforehand. To give the user a better chance to complete it without having to look at the solution.
