Overview: Prior to Orchid, items sorted by enumeration such that volumes displayed numerically (example v. 1, 2, 13, 20) instead by string (example v. 1, 12, 2, 20).  Sorting functionality should be re-introduced by enumeration.

Steps to Reproduce:
 # Log into the folio-snapshot environment.
 # Open Inventory and find the ABA Journal, inst000000000001.
 # Click on the Holdings record associated with the Main Library, hold000000000002.
 # Add a new item to the holdings record where the 'Enumeration' = v. 8 no. 1-6.
 # Click Save & Close.
 # Click the down-arrow next to hold000000000002 to display all items and sort by the 'Enumeration' column. 

Expected Results: The items list in either v. 8 no.1-6, v. 70 no. 1-6, v. 70 no. 7-12...... v. 73 no.1-6 OR v. 73 no. 1-6, v.72 no. 6-7,10-12, v. 72 no. 1-6......v.70 no. 1-6 order.  

Actual Results: The items list in v. 70 no. 1-6, v.70 no. 7-12......v.73 no.1-6, v.8 no. 1-6 OR v. 8 no. 1-6, v.73 no. 1-6, v. 72 no.6-7,10-12.....v. 70 no. 1-6 order.

Additional Information:  This functionality was originally implemented as part of UIIN-1412 and is discussed in the comments of .  Though  re-implemented item sorting, it did not return it to full previous functionality.  For any library with a large number of items attached to a holdings record, sorting by the enumeration is critical to workflow.
