Comparing text lists.

Help – been up all night and brain is flat…

I have a text list, which I need to compare with n-amount of other lists.  IE:

Original list: “beer, whisky, wine, vodka, tequila”

Then I have:

List 2: “beer, chocolate, nuts”

List 3: “whisky, bacon, beer”

List 4: “chocolate, bacon”

Etc…

I need a script that compares my original list with list 2, 3 & n, and return the list number that matches ANY of the list elements.  IE my result set would be “2, 3”.  (the ID of the lists returned as a valuelist)

Bonus point if you can arrange them by the amount of matches – “3, 2” – but non-essential. 

Point me in the right direction please!
