Maybe just use something like this ...
Code:
if [[ $(date +%a) = "Tue" ]] && [[ $(date +%d) -ge 8 ]] && [[ $(date +%d) -le 14 ]]
then 
     echo 2nd Tuesday
fi

TO run on Last day of every month
Code:
00 08 * * * [ `date +%d` -eq `echo \`cal | awk '{print $NR}'\` | awk '{print $NF}'` ] && /your_script_path/your_script.sh

A bit of explanation:
----------------------
cal : Gives the Calendar of that very month
$NR: Number of Records
$NR: Number of Fields

using "awk" command we are first getting the last line of Calendar Matrix, and then getting the last field of that line viz. last day of that month.

and Finally equating with the current Date

Hope this helps

I needed to run a script on the last day of the month as well. This is what I use....

Code:
#! /bin/ksh
# script to check for tomorrows date, usefull for running
# processes on certain day of the month; 
# TZ=CST+24 date +%Y-%m-%d (yesterday)
# TZ=CST-24 date +%Y-%m-%d (tomorrow)

if test `TZ=CST-24 date +%d` = 1; then
   myscript.sh
fi

Then put in a crontab entry like so

Code:
0 23 * * * /location/of/script/myscript.sh 2>&1 >> endofmonth.log
