Hi ikegami, Thanks again but it didnt succeed in sorting the numbers inside the brackets. This is the result: 
a1_1[2] a1_1[1] a1_1[10] a1_2[2] a1_2[1] a1_2[10] a1_10[2] a1_10[1] a1
+_10[10] a2_1[2] a2_1[1] a2_1[10] a2_2[2] a2_2[1] a2_2[10] a2_10[2] a2
+_10[1] a2_10[10] a10_1[2] a10_1[1] a10_1[10] a10_2[2] a10_2[1] a10_2[
+10] a10_10[2] a10_10[1] a10_10[10]

It sorts well the "words" but the order inside the brackets for some reason is 2 1 10. Any suggestion? Thanks.
