Running a TCL script through EEM every 60 seconds

Question

I have a script written in the TCLSH of IOS, I can test this script from the shell using the following commands
LAB-RTR#tclsh
LAB-RTR(tcl)#source flash:test.tcl
 NO CALLS
Is there a way I can run this test.tcl script every 60 seconds on the router.
SCRIPT test.tcl
proc get_ints {} {
set syslog [open "syslog:" w+]
#puts "BEFORE\n"
set check ""
set int_out [ exec "show voice call status\n" ]
#puts "INTOUT $int_out\n"
set mylist [regexp -nocase -line -inline {(^([0-9]*|No) active calls? found)} $int_out]
#puts "MYLIST $mylist\n"
foreach int $mylist {
 #puts "INT $int\n"
 if {$int == "No"} {
  puts " NO CALLS\n";
  puts $syslog "NO CALLS"
 } elseif {[string is integer -strict $int]} {
  puts "$int CALLS\n";
  puts $syslog "$int CALLS"
 } else {
  #puts "GARBAGE\n";
close $syslog
#puts ""
puts [eval get_ints]

Hey Joseph, Thanks for all your help. I have one last question, so now that I am running my script every 60 seconds if there is an issue I send multiple traps to our monitoring system. Is there any way you can keep track if the trap was already sent I will not send another trap again.
One way I can think of is using a loopback interface. But I would prefer not shutting down the loopback interface just to keep track of what my script is doing.
IF issue {
   IF Loop1 is up {
            don't send trap
    } ELSE {
            bring Loop1 up
            Send Trap
 } ELSE (No issue) {
   shutdown Loop1
