I used to do this ages ago, I did it by setting MEDs on the incoming BGP
prefixes, in my route-maps I arbitrarily gave some nets (/8s or smaller) lower
med on one feed and higher on the others to influence path selection.
I shy away from anything but the gentlest of tweaks so I personally wouldnt mess
with as-path, localpref, weight etc
