Custom columns with PHP code not supported in service Views module ?

Issue Summary

My environment is as follows -
Drupal 6.22
Services 6.x-3.1
Services Views 6.x-1.x dev

I am using the services views module to fetch some views, working fine with views containing all Drupal DB fields.
If I add custom columns (using PHP code) in the view result set, the service views module does not return these.

If the view is run on Drupal, the computed columns are seen in the result set; but the service views API does not seem to return these computed column.
I tried searching through the issues to see if anybody has logged this before. No luck.

Has anybody experienced this behavior ?
Can someone help here ?

Thanks in advance,
