EDIT: Thanks toAlexey Matveev the script is now working and all questions are solved

Below the edited script which works for JIRA 7.4.x Server

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.CustomFieldManager
import com.atlassian.jira.issue.MutableIssue
import com.atlassian.jira.issue.priority.Priority
import org.apache.log4j.Logger
import org.apache.log4j.Level
import com.atlassian.jira.event.type.EventDispatchOption

def currentIssue = (MutableIssue) issue
CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager()

//switch depending on the values of custom field and set priority accordingly
switch (customFieldManager.getCustomFieldObjectByName("Name of custom field").getValue(currentIssue).toString())

{
case "1. First value custom field":
currentIssue.setPriorityId(ComponentAccessor.getConstantsManager().getPriorities().find{it.getName().equals("Here goes the first priority name")}.getId());
break;

case "2. Second value custom field":
currentIssue.setPriorityId(ComponentAccessor.getConstantsManager().getPriorities().find{it.getName().equals("Here goes another priority name")}.getId());
break;

case "3. Third value custom field":
currentIssue.setPriorityId(ComponentAccessor.getConstantsManager().getPriorities().find{it.getName().equals("Here goes the last priority name")}.getId());
break;

default:
break;
}

// Update Issue
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
ComponentAccessor.getIssueManager().updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

Hello,

1. You can find IDs of priorities if you go to cog item->issues->priorities and then hover on the edit item.

2. If you want to save the issue then add your post-function first in the list of post functions or add to the script in the first line

import com.atlassian.jira.event.type.EventDispatchOption 

and add to the end of your script

def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser()
ComponentAccessor.getIssueManager().updateIssue(user, issue, EventDispatchOption.ISSUE_UPDATED, false)

You updated the script. So what are now your questions? Are they the same?

Hi Alexey, 
thanks for your answer - problem 2 saving the issue is solved!!!

However, I was still not able to find the ID of priority. 
We use JIRA Server 7.4.x 
1. I go to issues --> Issue attributes -->Priorities
2. The list of the priorities is displayed

Problem:
When I hover over the link "Edit" in the column Actions there is no priority displayed
When I choose edit I can neither see nor change priority

Am I missing the meaning of " cog item"?

Thanks,
Sven

Do it another way 

change 

currentIssue.setPriorityId('3');

to

currentIssue.setPriorityId(ComponentAccessor.getConstantsManager().getPriorities().find{it.getName().equals("High")}.getId()))

Instead "High" you put your required priority
