RewriteRule matches aginstt just the path, without the scheme host or
query string.

That isn't the issue in this example. Notice that the rewrite rule pattern is simply "^" which will match any path as it simply tests that the path has a beginning (i.e., it anchors any subsequent part of the pattern to the start of the path).

My question for James would be how do you know the query string has the parameters in that exact order? Unless the query string has been hand-crafted you cannot assume the parameters will appear in any specific order. Also, your pattern doesn't handle the case where the parameters are separated by semicolons (which is a legal alternative to ampersand). In general matching against QUERY_STRING is very difficult to do in a robust manner.
