These are the well known ports from IANA. Basically it means if you use one of these
adhoc you run the risk of breaking something - now or next week. Just because a port is unused right now does not mean it won't get used again soon.
Is there a reason you have to use low number ports?
Try something like this:
You could also create an array (port based) on the awk output and search through the array rather than using grep. Use the mapfile command, which creates an array named MAPFILE with every port number in it. You can also use associative arrays to speed up your search. None of this is really useful except when you are creating lots of ports.

portreserve
PORTRESERVE(1) TCP port reservation utility PORTRESERVE(1)NAME
portreserve - reserve ports to prevent portmap mapping them
SYNOPSIS
portreserve
DESCRIPTION
The portreserve program aims to help services with well-known ports that lie in the bindresvport range. It prevents portmap (or other
programs using bindresvport) from occupying a real service's port by occupying it itself, until the real service tells it to release the
port (generally in its init script).
It is intended that portreserve runs from an initscript of its own, and services wishing to interact with it should use portrelease.
When the portreserve daemon is started, it examines the /etc/portreserve/ directory. Each file not containing "." or "~" in its name is
considered to be a service configuration file, and must contain a service name (as listed in /etc/services) or a port number. UDP services
may be specified by appending "/udp" to the service name, and TCP services by "/tcp". Several services may be specified, one per line.
For example, /etc/portreserve/cups might contain the string "ipp" or, equivalently, "ipp/tcp" and "ipp/udp" on separate lines.
For each service configuration file, a socket is created and bound to the appropriate port. A service wishing to bind to its port must
first run portrelease, which instructs portreserve to release the port associated with the service.
Once all the reserved ports have been released, the daemon exits.
