Ranges are charracter classes in regular expressions, not integer values, the range you created is 0..252 ie. the set (0,1,2,5,2) however ranges need to be used in a suitable tool rather than directly in the shell
One, horrendously complex, way of doing it would be to capture the digits and assess them separately like below, there is probably a much neater solution though...
Code:
$ myfile=vout123
$ export myfile
$ perl -e 'if ($ENV{myfile}=~/vout(\d+)/ && $1 >0 && $1 <253){print "t\n";}'
t
$
