Google Apps bounce processing - is the wiki current?
So first, the VERP setting you see is about processing replies, it isn't the same as the VERP used for the bounces, that are always in.

For the bounces, you need to create a mailbox dedicated for that purpose, (eg. return@domain.org) that is different than your normal sending email (info@domain.org). You could in theory use info@domain.org, but that's likely to create problems for your org.

To test if it works, create a contact with an invalid email address, send a civimail mailing to a group with that address and verify that the bounce email is properly into the return@domain.org mailbox. If it is, you are almost there, as your cronjob seems to be properly setup to fetch that mailbox.

As for the label:inbox-civimail-ignored, it is simply that you have an email in your "bounce/return" mailbox that isn't a bounce. One of the many reasons to keep your info@domain (where recipients might reply to) separated from your return@domain (where only the mail servers are supposed to reply to when there is a bounce).
