Are you talking about the tabs position in module manager?
If so you can simply type tabs in the select position box. Once you have typed it once it will be there forever more.
Unfortunately, it seems that some positions have been missed from the templateDetails.xml file.
If you do the above and simply type in in the box then it will work. Alternatively open the templates>ja_portfolio>templateDetails.xml file in a plain text editor such as notepad and find the following section.
<positions>
<position>slideshow</position>
<position>content-mass-top</position>
<position>hornav</position>
<position>breadcrumbs</position>
<position>search</position>
<position>banner</position>
<position>left</position>
<position>right</position>
<position>top</position>
<position>user1</position>
<position>user2</position>
<position>user3</position>
<position>user4</position>
<position>user5</position>
<position>user6</position>
<position>user7</position>
<position>user8</position>
<position>user9</position>
<position>user10</position>
<position>user11</position>
<position>footer</position>
<position>syndicate</position>
<position>debug</position>
</positions>
Add in there somewhere
<position>tabs</position>
And tabs will appear in the module manager dropdown. Me, I would just type it in the box.
