I have nothing more to add to Guy's really good explanation. But if you are using Wireshark 1.10.0, be aware that it 
comes bundled with a small utility (found in the installation folder) allowing you to reorder a capture file according to 
the packets timestamp. Simply do:

Having an option to do that within Wireshark might be useful as well.

(Having a way for libpcap/WinPcap to fix that problem might also be useful; that might requiring delaying the delivery of packets to 
libpcap's callers until you're pretty sure some packet with a time stamp before that packet won't arrive.)

Yes, it would be useful: we know that we can get packets out of order when capturing from multiple devices at the same time. See:

(In which I said that fixing the problem would be difficult if not impossible.)
