If I understood you correctly, this should get you close to what you want. Put your posts into an array first:

$posts = array();
while ( $loop->have_posts() ) {
    $loop->the_post();
    array_push($posts, $post);
}

Then sort that array. I'll demonstrate with 0-9:

$array = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);
$first = array_slice($array, 0, 3);
$second = array_slice($array, 3, 4);
$third = array_slice($array, 7, 3);
shuffle($first);
shuffle($second);
shuffle($third);
$newarray = array_merge($first, $second, $third);
print join(", ", $array) . "
" . join(", ", $newarray) . "
";

Which will lead to a random-ish sorting of the array while keeping "blocks" (top, middle, bottom) in the same order:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9
1, 2, 0, 6, 5, 4, 3, 8, 7, 9

0, 1, 2, 3, 4, 5, 6, 7, 8, 9
0, 2, 1, 3, 4, 5, 6, 9, 8, 7

Putting it all together:

$posts = array();
while ( $loop->have_posts() ) {
    $loop->the_post();
    array_push($posts, $post);
}

$first = array_slice($posts, 0, 3);
$second = array_slice($posts, 3, 4);
$third = array_slice($posts, 7, 3);
shuffle($first);
shuffle($second);
shuffle($third);
$newposts = array_merge($first, $second, $third);
foreach($newposts as $mypost) {
    print $mypost->post_title . "<br />
";
}

note that I erroneously had written push $posts, $post; instead of array_push($posts, $post);, I have written a lot of Perl lately, and it shows.
