AP Checks - Group By Amount (<5000 and >=5000, then sort Alpha on RTF

Within our company, all checks $5000 and over must be hand-signed; any under this are 'auto-signed'.When a check batch is printed, we would like all checks that are $5000 and over to print first, in alpha order - then those under $5000 in alpha order.
I'm using an RTF template to do this.

Using format_payments_evergreen - (APXPBFEG) - elements that matter listed below
<LIST_G_CHECKS>
   <G_CHECKS>
       <C_CHECK_AMOUNT>5001 </C_CHECK_AMOUNT>
       <C_VENDOR_NAME>SAMPLE COMPANY </C_VENDOR_NAME>
   </G_CHECKS>
   <G_CHECKS>
       <C_CHECK_AMOUNT>400 </C_CHECK_AMOUNT>
       <C_VENDOR_NAME>COMPANY B</C_VENDOR_NAME>
