From memory, I don't think 1.2 has a CSV import option for Songs, this is for Bibles. However we haven't supported 1.2 for quite some time.

You should really be upgrading to 2.0.1. This has numerous import options, for a number of different worship programs. The default is an XML format, see http://openlyrics.info/ if you can export to this.
<br>
However the option to import Zionworx songs expects a CSV format and looking at the code it appears to want the following columns:
<br>
ignored, "Main Title", "Alternate title", "Lyrics", "Authors", "Copyright", ignored, ignored
<br>
For the lyrics, the verses are separated by blank lines.
