Google consider dashes ("-") in the requests as synonyms of spaces (" "). However, I don't see any situation where anyone would type the keywords appearing in my blog's URLs using dashes ("-") or underscores ("_") where those should be considered as spaces.
As blogger, I choose either to type only relevant keywords (separated by underscores) in my URLs, either leave them empty, letting b2evolution using the title to build the URL. Moreover, I consider using underscores appears to be more readable for humans (isn't Google recommanding to optimize a site for humans and not for robots?)
I really don't see any difference between dashes and underscores for Google positioning...
(Dashes are used in main domains because underscores are not authorized there, are they?)
Finally, that might be a feature to choose the separator you want to (or to avoid using any separator; Google doesn't care about word separators in URLs while it does in a web page.)
