Efficiency is biting you here.
The footer output works, but scripts still need to be enqueued before
the wp_head call. Even footer included ones.
The reason has to do with the way the print_scripts calls work. The
first one called from wp_head processes all the enqueued scripts. If
it see a footer one, it saves it in an array called "in_footer". The
print_footer_scripts then prints those out later.
So enqueueing in the middle of the page won't do you any good. After
wp_head, the scripts are fixed. What is known to be included has
already been decided, you can't add anything later.
If you want to determine whether a shortcode is used or not to include
a script, you have to scan ahead to the content. Write your own Loop
to look for the shortcode, then do a rewind to reset the loop for
another go-through by the main page.
