Circuit connection to "ground": does order matter?

I am building a small amp: <http://hackaweek.com/hacks/?p=131>Does the order in which I connect the "grounds"  on the cb matter as long as they are all interconnected? Diagram available at: <http://hackaweek.com/hacks/?attachment_id=132>.

Not really.

Any order will work for this one, there are some cases when it does matter, but this isn't really one of 'em.
