Which stats test to use?

#1
Hi

I have two lists (for example), as follows:

1: Horses
2: Houses
3: Cars
4: Cats
5: Bananas
6: Shovels
7: Boats
8: Sheep
9: Forks
10: Spoons


1: Cats
2: Cars
3: Houses
4: Forks
5: Spoons
6: Shovels
7: Horses
8: Boats
9: Bananas
10: Sheep


The two orderings have been produced by two different algorithhms and I want to know what stats test I should use to ascertain if the orderings are statistically different?

Also, how many items do I realistically need for the test to be meaningful?

Thx
