arrays in custom properties--not possible?

[Sannyasin Sivakatirswami]

on storePrefs
   repeat with x = 1 to (the number of fields of this stack)
     put  fld x into gPrefsArray[the short name of fld x]
   end repeat
   set the cPrefs of this stack to gPrefsArray
end storePrefs

the above fails, apparently because the attempt to set a custom 
property to an array is unacceptable. Is this a known limitation? "Tell 
me its not so..."
