Select2 tag re-ordering and 'acts as taggable on' gem

Select2 tag re-ordering and 'acts as taggable on' gem

I have an options list in my params hash which I have re-ordered using
select2 as such:
"option_list"=>["3,1,2"]

Unfortunately this seems to have no effect on the ordering of the tags
saved by the gem:
Style.last.options
=> [#<ActsAsTaggableOn::Tag id: 20, name: "1">, #<ActsAsTaggableOn::Tag
id: 18, name: "2">, #<ActsAsTaggableOn::Tag id: 17, name: "3">]
