Is there a nodequeue module for ordering and selcting taxonomy terms instead of nodes for used in a view?
You can try out Flag module, which supports flagging entities, combined with flag_weights and draggableviews you can create ordered slideshows of flagged taxonomy terms.


  Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, users, and any other type of entity. Some possibilities include bookmarks, marking important, friends, or flag as offensive. With extensive views integration, you can create custom lists of popular content or keep tabs on important content.


If you want to use Flag-3.x with flag_weights you will have to apply this patch: https://drupal.org/node/1877304 works for me so far.
