That doesn't quite give the output the OP requested, and will fail for multi-digit "ch.." values.

If the entries always start with "ch", this code should work:

perl -e 'my @arr = ( [ ch1=> 100 ], [ ch2=> 20 ], [ ch11=> 13 ], [ ch2 +=> 45 ], [ ch1=> 1 ] ); @s= sort( { substr($arr[$a]->[0],2) <=> sub +str($arr[$b]->[0],2) or $arr[$a]->[1] <=> $arr[$b]->[1]} 0..$#arr);pr +int qq|@s\n|' #Output: #4 0 1 3 2
Note - OP's data has been modified slightly - adding a 2-digit "ch" value ("ch11").

Also - this is not the most efficient sort for this kind of data, but will work well for small to medium size data. More complex transforms are required for efficiency with large amounts of data (For some definition of 'large').
