I know it is not important in this case since @values is so small but on larger arrays a Schwartzian Transform might be in order. This example will take care of cases where the number of digits is not the same. 
my @values = (
    '123=more digits',
    '04=critical',
    '02=informational',
    '01=unknown',
    '10=test',
    '03=warning',
    '08=foo',
);
@values = map { $_->[1] } 
            sort { $a->[0] <=> $b->[0] } 
                map { [/(\d+)/, $_]} 
                    @values;
print join "\n", @values;
__OUTPUT__
01=unknown
02=informational
03=warning
04=critical
08=foo
10=test
123=more digits
