Read It Later plugin does not save the tags for web sites all the time
Read It Later does not preserve the tags assigned to websites in some cases. Sometimes I go through the list, assign tags, close the browser hoping it would write all the changes to the internal database (readItLater.sqlite) and after reopening the browser, some sites have the tags and some don't.

Upgrade your browser to Firefox 8 and check
@Swarnava. Thank you, but for now I would disregard your response, since I'm not planning to upgrade and I've seen posts where people have the same issues with the latest version of 8.0.1
Try using Read It Later support for help with that extension.
