(rephrased as I'm not sure how much quoting is allowed and erring on the side of caution)

From B558, the DR for 2" of stone should be 312. As I understand it, the armor divisors would stack by multiplying to 6. That leaves us needing to deal 53 damage to overcome the stone wall's DR.

A bow deals thrust+2 impaling, so to deal 53 damage it looks like we'd need to be rolling 9d before that was possible. That seems unlikely.
That's the DR for two feet of stone. The DR for a 1-foot stone wall is DR156, and it seem to be linear, so for two inches it would be 156/12 x 2 = DR26. Halve that for chinks for DR13, and with divide by three (rounding down) for the (3) penetration modifier and it gives DR4 vs the arrow, and five or points of damage means you've got your rope arrow stuck into the wall.
