date format in script text eidtor

In the script text editor if I have to give Less than equal to sep 22nd 2010,

should I follow like

IF &EKKO-BEDAT& LE 09/22/2010 or

IF &EKKO-BEDAT& LE 22/09/2010 or

IF &EKKO-BEDAT& LE 22092010 or

IF &EKKO-BEDAT& LE 09222010 or

IF &EKKO-BEDAT& LE '22.09.2010'.

In the table it is getting stored as 09/22/2010 ie sep 10th 2010.In Script debugging it is showing as 22.09.2010.

Thanks,

K.Kiran.
