on render_tabs helper, label, which is translated on view, don't accept translation arguments. A simple change on view allows to do this:

  <%= render_tabs [
    {:name=>'issued',:partial=>'issued_invoices',:label=>:issued},
    {:name=>'received',:partial=>'received_invoices',:label=>[:received,{:num=>"3"}]}
  ] %>
