Here's a quick one. It does assume there's only one (unwrapped) line of
text in the field:

on verticalCenter theFieldName
  put the effective textHeight of field theFieldName into myHeight
  get the height of field theFieldName - myHeight
  set the topMargin of field theFieldName to it div 2
end verticalCenter
