I just noticed something else which may explain the increased wear.
I recently got another engine block back from a machine shop who bored and honed it, and I just noticed that my honing marks on this scored engine are much deeper and scratchier than those done by the machine shop on the other engine block - so this may have lead to increased wear and metal particles in the oil which caused the scoring.
The lesson? Don't use a cheap hone, and use plenty of oil on it I guess!
