[TYPO3-mvc] How I can do manual sorting by storagePid

[Дмитрий Васильев]

In my extension written by Extbase, I define storage folder: 
plugin.tx_myext.persistence.storagePid = 1,2
My extension installed on different pages, which need different sorting 
records.
I want to do manual sorting, like plugin.tx_myext.persistence.storagePid 
= 2,1
But it does not change. How I change the sort order by storagePid?
