[consulting] Views sorting (radioactivity + date + smth else...)?

[Audrius Naslenas]

Dear drupalers,

Have one simple views question:
Is it possible to sort view by some calculated number, lets say:
radioactivity value * datestamp integer value ?

Or: comment count * times node viewed ? 

Have one project, where I want to make node weights a bit "smarter" than
just submission date or voting results. It could be a formula, which is
calculated using 2 or more values.

How?

Thank you in advance.
