I have been continuing the process of analysis by using a latest
version of wireshark. I just now verified with Version 1.2.5 (SVN Rev
31296) on Windows OS, it seems to display the 'TCP options' field
properly. But, I wonder why the 0.99.0 version (linux) does not
display it.  Just as you have conveyed that it is displaying for
0.99.6(Linux) version, i too think that it should work for 0.99.0
version also. I will re-analyze the logs of version 1.2.5(Windows) and
0.99.0(Linux) and check the Connection establishment and TCP Call
flow.

Thx in advans,
