Sure Start Maternity Grant?

I know you can only claim the Sure Start Maternity Grant one off 500 pounds if you are on job seekers, income support ect on the date you claim for the grant. But will it make a difference to whether or not you can claim it if you done 2 months part time work (only 1, 2 or 3 days a week, each week varies) 3 or 4 months before the date you claim? As you are still on job seekers on the date you are claiming, you haven't worked for 3/4 months and before the 2 months temp work you were also on job seekers. 1 or 2 days work a week is no more money than job seekers anyway! Does anybody know or been in this situation before?
