could run the script below and provide output using code tags!
Code:
#!/bin/bash

DISCOVERY ()
{
   addr="${1}"
   echo "DISCOVERY [${addr}]"
}
PORTS ()
{
  addr="${1}"
  echo "  PORTS [${addr}]"
}

while read address junk
do
   DISCOVERY "${address}"
   PORTS "${address}"
done < activeips.txt

I don't see anything wrong with this output
your DISCOVERY for 1st address:
Code:
Starting Nmap 7.60 ( ) at 2018-04-04 16:39 CDT
Nmap scan report for sd10.ssi.private (10.0.0.13)
Host is up (0.86s latency).

your PORTS for 1st address:
Code:
PORT STATE SERVICE
21/tcp closed ftp
22/tcp closed ssh
23/tcp closed telnet
25/tcp closed smtp
53/tcp closed domain
80/tcp closed http
110/tcp open pop3
111/tcp closed rpcbind
135/tcp open msrpc
139/tcp closed netbios-ssn
143/tcp open imap
443/tcp closed https
445/tcp open microsoft-ds
993/tcp open imaps
995/tcp open pop3s
1723/tcp closed pptp
3306/tcp closed mysql
3389/tcp closed ms-wbt-server
5900/tcp closed vnc
8080/tcp closed http-proxy

and so on....

Here ya go....this is the part that doesn't make sense....

In this output...for your test script....it LOOKS like they run back and forth

Code:
DISCOVERY [10.0.0.13]
  PORTS [10.0.0.13]
DISCOVERY [10.0.0.16]
  PORTS [10.0.0.16]
DISCOVERY [10.0.0.22]
  PORTS [10.0.0.22]
DISCOVERY [10.0.0.17]
  PORTS [10.0.0.17]
DISCOVERY [10.0.0.19]
  PORTS [10.0.0.19]
DISCOVERY [10.0.0.20]
  PORTS [10.0.0.20]
DISCOVERY [10.0.0.12]
  PORTS [10.0.0.12]
DISCOVERY [10.0.0.11]
  PORTS [10.0.0.11]
DISCOVERY [10.0.0.15]
  PORTS [10.0.0.15]
DISCOVERY [10.0.0.24]
  PORTS [10.0.0.24]
DISCOVERY [10.0.0.63]
  PORTS [10.0.0.63]
DISCOVERY [10.0.0.62]
  PORTS [10.0.0.62]
DISCOVERY [10.0.0.80]
  PORTS [10.0.0.80]

But...as we run the actual nmap commands, I'm thinking that since the first one doesn't finish it as quick as the second one does, the second one just jumps to the next address and the next and the next. Maybe the syntax is all right, but we need a way to tell PORTS to wait for DISCOVERY to finish before they continue on to the next ip?

everything makes sense.DISCOVERY runs first - then PORTS runs one address at a time.
Your real script is a bit noisy in the output, but it produces output in the expected order.

To illustrate, here's your script with steps:
Code:
#!/bin/bash

DISCOVERY ()
{
   addr="${1}"
   echo "DISCOVERY [${addr}]"
   nmap -v -p 139,445 --script=smb-os-discovery "${addr}" |grep -v 'smb-os-discovery' | grep -v 'OS CPE' | grep -v 'Computer name' | grep -v 'NetBI'
}
PORTS ()
{
  addr="${1}"
  echo "   PORTS [${addr}]"
  nmap -sT --top-ports 20 "${addr}"
}

while read address junk
do
   DISCOVERY "${address}"
   PORTS "${address}"
done < activeips.txt
