For all entries sorting problem

I have a problem sorting data when for all entries is used

for example i got it_pernr like this

row pernr

1 5

2 2

3 8

Then i got the selection

SELECT pernr test_column

FROM test_table INTO CORRESPONDING FIELDS OF TABLE it_test_table

FOR ALL ENTRIES IN it_pernr

WHERE pernr = it_pernr-pernr

AND begda <= sy-datum

AND endda >= sy-datum.

After selection i got table it_test table like this :

row pernr test_column

1 2 test2

2 8 test8

3 5 test5

So my question is how can I sort it like this ( like in it_pernr):

row pernr test_column

1 5 test5

2 2 test2

3 8 test8

Thanks in advance 😊
