page names, delimeters, and near-duplicate content

[Tonearm]

I've gotten my pages that display multiple products (category pages, etc.) to have page names like this:

keyword-1-1-1.html

The keyword is there to help the page's ranking and also to potentially be used in incoming link text. The numbers are there to keep track of certain things about the page (page number, page type, and sorting type).

Will all of the dash delimeters hurt my ranking? I'm thinking Google might see the above page as having 4 keywords instead of one.

Also, since the third number in the page name is the sort type, and there are two types of sorting, each page like this:

keyword-x-x-1.html

can also be accessed like this:

keyword-x-x-2.html

and each page has a link to the "alternate" page. How will Google handle this since the two pages will be the same except for different sorting?
