AS prepend tends to be only for inbound traffic, to influence outbound you can 
use a few different BGP attributes. There is a pecking order (at least in 
Cisco) as per below:

Weight
Local preference
Multi-exit discriminator
Origin
AS_path
Next hop
Community

Cheers,

P.

The most common method is to prepend your AS number to the path that
you announce to the ISP that you want to de-prioritize.
You would use set-bgp-prepend on the inbound route filter for the
connection that you want to de-prioritize. I'd prepend 1, wait a
couple of days and then prepend 2 if necessary.
