I had the same problem and solved it with the help of a little hack:
open the file:
media/plg_system_eprivacy/js/eprivacy.class.min.js and search for the string
var decline=$('<button class="decline '+root.vars.declineclass+'">'+root.translate('DECLINE')+'</button>').appendTo(ribbon);var accept=$('<button class="accept '+root.vars.agreeclass+'">'+root.translate('AGREE')+'</button>').appendTo(ribbon);
and change the ordering in which the decline and agree variables are appended to the ribbon.
var accept=$('<button class="accept '+root.vars.agreeclass+'">'+root.translate('AGREE')+'</button>').appendTo(ribbon);var decline=$('<button class="decline '+root.vars.declineclass+'">'+root.translate('DECLINE')+'</button>').appendTo(ribbon);
Be aware that, until some sort of plugin template comes, you will have to do this each time after you update the plugin.
