High_CPU is always a decimal from the top command. Does that help?

Put the script in set -x and debug it from there.
This is the output from set -x

[dbtlst@asdv-snsc-tlst ~]$ sh cputest.sh
+ top -b -n 1
+ head -8
+ sed -e 1,5d /tmp/cpu.text
++ cat /tmp/cpu2.text
++ tail -1
++ awk '{print $9}'
+ High_CPU=57.9
++ hostname
+ host=asdv-snsc-tlst.dsns.cdc.gov
+ '[' 57.9 -gt 90 ']'
cputest.sh: line 7: [: 57.9: integer expression expected
+ exit
