Make copyright section into 3 columns

I am trying to make the copyright section of the webpage into 3 columns using Tom's Lightweight Grid Columns. I have been successful at inserting 2 columns on the same row, however the third column moves to the row below.

The design is simple . . . copyright on the left, my logo in the center and social icons (4 small ones) on the right.

Thanks for any help.

p.s. I did move the copyright to the left using Tom's CSS code (posted from another copyright topic).
