I can't tell if the pasted code is the style you want, or the style that isn't working for you. Assuming the first, perltidy -bli -i=2 -et=2 produces something close to what you posted.

For example:

$ echo -e "sub testing\n{\nx=1;x++;if(1){\nx--;\n}\n}\n" | perltidy -b
+li -i=2 -et=2
sub testing
        {
        x = 1;
        x++;
        if (1)
                {
                x--;
                }
        }

$ echo -e "sub testing\n{\nx=1;x++;if(1){\nx--;\n}\n}\n" | perltidy -b
+li -i=2 -et=2|hexdump -c
0000000  s   u   b       t   e   s   t   i   n   g  \n  \t   {  \n  \t
0000010  x       =       1   ;  \n  \t   x   +   +   ;  \n  \t   i   f
0000020      (   1   )  \n  \t  \t   {  \n  \t  \t   x   -   -   ;  \n
0000030 \t  \t   }  \n  \t   }  \n  \n
