Do you work for TAC? Cisco IOS 10.3 could certainly handle ping just fine. ;-) I have a guess. Notice that the serial link has a subnet mask of 255.255.255.252. This is a subnet mask that you typically see on a point-to-point link with just two devices on it (the routers at either end). The link has no purpose other than to connect the customer's LAN to the ISP. Hence, there's no reason for the ISP to advertise a route to that point-to-point 100.20.90.56/30 network. In fact, for security reasons, it's probably a good idea to make sure there is not a route to this dedicated network that has just two memebers, the two router interfaces. So, this means that there's no way for a ping reply to get back to the 100.20.90.58 address. Now, the LAN is addressed with a network number and subnet mask that you might see used for a typical small customer (60.80.200.113 255.255.255.240). Undoubtedly, there are no problems getting back to this LAN. The fact that he can surf the Web proves that point.
