Dear Monks

Can anyone of you advise me if there is some module on CPAN or algorithm to search incremental expressions with regexps or by some predefined pattern

ie "4321234" =~ /(\d)\A1\A2\A3/ where we assume that A1 = $1 + 1 , A2 = A1 + 1, ...

My problem is I should implement some algorithm that returns a category of a given number string. ie 

 
get_category("10000") = 10 # best category
get_category("12345") = 10 # good category
get_category("54321") = 8 # average category

So I want to set some rools for each category with regexps or regexp like patterns. The only problem is how to search incremental expressions with regexps or how to effectively implement it by myself
Thanx, Alex
