You don't have an "else bucket"; dothis_2 will be executed if either the numerical test or dothis_1 fails.

Code:
[ $var -lt 1 -o $var -gt 50 ] && dothis_1 || dothis_2

Code:
if case $var in
*[!0-9]* | "" ) false ;;
*) true ;;
esac && [ $var -ge 1 ] && [ $var -le 50 ]
then
echo dothis_1
else
echo dothis_2
fi
