If you take a look at the command reference for the as-path command: http://www.cisco.com/en/US/docs/ios/iproute_bgp/command/reference/irg_bg p4.html#wp1136246
You would see that the "prepend" keyword would work only on ingress or egress BGP route-maps: "Appends the string following the keyword prepend to the autonomous system path of the route that is matched by the route map. Applies to inbound and outbound BGP route maps." In the link above there are also details about specific 4-byte AS support.

Re guys, the prefixes I give out are being rooted by "network" entries with a route-map attached (like "network a.b.c.d/e route-map <rm>"). In that route-map, I'm simply prepending an ASN ("as-path prepend <as>"). Well - that prepend never makes it to the outside world. Source ASN is simply my ASN, the desired <as> is nowhere to be found. Am I wrong in assuming it should work that way? Oh, platform is an ASR1002, IOS-XE 12.2(33)XNC1t. Didn't try my 7301s yet...
