No, there are 7! = 5040 possibilitys, like DigDog said.
Yes Hrainin, so you can find out a few orders between the pears, and so reduce the possibiltys for the right complete order.
I've started it like this.
But it's annoying to play every time the tutorial from the beginning. And it's even more annyoying if you then make silly mistakes and miss the secret level....
But I'm on a good way to the right order

61990 points in tutorial (and i remember 1 more coin there which i didnt find)
and there really are lots and lots of different combinations
1,2,3,4,5,6,7
1,3,2,4,5,6,7
1,2,4,3,5,6,7
1,2,3,5,4,6,7
1,2,3,4,6,5,7
1,2,3,4,5,7,6
1,4,2,3,5,6,7
1,5,2,3,4,6,7
etc etc, you get the idea
Permutation is the magic word Billybob
Anyway, I made a screenshot so that we can plan this better:
i40.tinypic.com/2vt8rdj.pngIf you want to post any combinations you tried, please use the numbers I provided on the screenshot.
I had the idea of trapping all of them in one place and kill them with one single bomb, but it doesn't work because of the placement of 3, 6 and 7.
It would be possible to kill 1, 2 ,3 ,4, 5 at the same time, and kill 6 and 7 at the same time.
It should also be possible to kill 3 seperately, and kill 1, 2, 4, 5, 6, 7 all together.
