Jak dodać skrypt do strony opartej na WordPress?

Witajcie!
Potrzebuję pomocy przy pisaniu czegoś co wywoła javascript.

var autoCompleteData = {
    teams : [
      ['fi:Player 1', ''],
      ['', '']
    ],
    results : []
  }
 
/* Data for autocomplete */
var acData = ["kr:MC", "ca:HuK", "se:Naniwa", "pe:Fenix",
              "us:IdrA", "tw:Sen", "fi:Naama"]
 
/* If you call doneCb([value], true), the next edit will be automatically 
   activated. This works only in the first round. */
function acEditFn(container, data, doneCb) {
  var input = $('<input type="text">')
  input.val(data)
  input.autocomplete({ source: acData })
  input.blur(function() { doneCb(input.val()) })
  input.keyup(function(e) { if ((e.keyCode||e.which)===13) input.blur() })
  container.html(input)
  input.focus()
}
 
function acRenderFn(container, data, score) {
  var fields = data.split(':')
  if (fields.length != 2)
    container.append('--')
  else
    container.append('<img src="site/png/'+fields[0]+'.png"> ').append(fields[1])
}
 
$(function() {
    $('div#autoComplete .demo').bracket({
      init: autoCompleteData,
      save: function(){}, /* without save() labels are disabled */
      decorator: {edit: acEditFn,
                  render: acRenderFn}})
  })

Mój java script wygląda tak, kompletnie nie mam pojęcia jak to dodać do strony opartej na wordpressie.
