I don't use MongoDB much and you didn't provide a working script to start with so I can't really provide an answer. I can however point you to a snippet of code that I found that might help. I did a Google search for "perl mongodb slice" without the quotes and the fifth result was Example of using $slice and fields() in the MongoDB Perl driver 0.45.
