Updating Price Level field Sales Order, will attached script fail after X line items?

I have tested the attach script and it works. But before I deploy the attached script to the Sales Order, I was hoping that someone could review my script and comment to the NEGATIVE potential of the script or suggest a better optimized script. (ex. after 200 items, the script will not update line items).

Overview

Added a custom select field mirroring the (Internal ID) values of the Item Price Level Field.

Script triggers when end user selects a value from the Custom Select Field.

   function setPriceLevelOverride(type, name){      if (name == 'custbody_plo') {                        var PriceLevel = nlapiGetFieldValue('custbody_plo');                            for (var i = 1; i <= nlapiGetLineItemCount('item'); i++) {                  nlapiSelectLineItem('item', i);                  nlapiSetCurrentLineItemValue('item', 'price', PriceLevel, false, true);                  nlapiCommitLineItem('item');              }                            return false;          }        }
