You could try using Osaka 
plugin for your sorting

  You 
  could convert DateNum() to a DateIndex which will be a much smaller number. 
  You would have to pick a first date for zero, your reference, or count 
  backwards from today... depend on your application. 
  <SPAN 
  class=937203802-21022004> 
  The 
  DateIndex would simply be the number of bars before a given point. 
  <SPAN 
  class=937203802-21022004>For 10 years you should have a maximum count of about 
  10*250=2500 which is much smaller than you datenum. 
  <SPAN 
  class=937203802-21022004> 
  <SPAN 
  class=937203802-21022004>Interesting problem,
  good 
  luck,

    Can anyone help me Sort this out....Has anyone yet got 
    around the DateNum() / 32 bit float limitation yet?This is a real 
    Turd of a problem - And I'd like to know if there are any 
    workarounds/solutions?For me - I wish to Transform DateNum() to a 
    Ranking system I can sort under AA.But two limitations are stoping 
    me.1) The use of Strings in AB appears to be as single variables. (Not 
    Arrays).2) Transforming the value from DateNum creates a number greater 
    than 7 significant digits. Inducing the 32bit Float limitation.For 
    those unaware of the above constrictions, Here is a sample AFL to show 
    you.// Combined Sort 
    for AA.//// Filter = "Curent Stock"//// Range  = "All 
    Quotes"// Create a Date/Rank to Sort with.//// Doesn't work
