custom query to get posts

I want to create custom links like

mydomain.com/custom_page/cat=ABCtag=XYZ

So that when a user clicks on the link s/he can see all posts in the category 'ABC' having tag 'XYZ'

For this I've created a custom template with the following code

?php
/*
Template Name: MyCustomTemplate
*/
?

?php get_header(); ?
global $wp_query;
get_query_var( 'cat' );
get_query_var( 'tag' );
?php get_footer(); ?

I don't know how to query for the posts in the category 'ABC' with the tag 'XYZ'

I checked http://codex.wordpress.org/Function_Reference/query_posts#Passing_variables_to_query_posts

but the examples shown there use 'static' values. I need to query using dynamic values: which are passed via the URL.

Also, I'm using a plugin 'Advanced Custom Fields' and have added a field 'priority' with the defult value 'Z'. I intend to assign one alphabet to each post in the priority field, so that results on the page are served sorted according to "priority" : Posts with the priority 'A' on the top, followed by posts with priority 'B' and so on..

In Short:

I want to get category and tag parameters from links like:

mydomain.com/custom_page/cat=some_categorytag=some_tag

Then Fetch posts in the category 'some_category' AND having tag 'some_tag' AND sorted according to custom field : 'priority'

You can get variables from $_REQUEST, but you must first reset permalinks to default format and make sure this is correct variable names. In your case it's $_REQUEST['cat'] and $_REQUEST['tag'], so the dynamic query will be

$args = array(
  'post_type' => 'post',
  'category_name' => sanitize_title_for_query( $_REQUEST['cat'] ),
  'tag' => sanitize_title_for_query( $_REQUEST['tag'] ),
  'meta_key' => 'priority',
  'orderby' => 'meta_value_num'
);

Clarification of your question:
You want to show Posts of a certain category named "ABC" AND also you want to filter the posts with the tag named "XYZ".

Answer:
If this is the scenario, have you tried: WP_Query()?

<?php    
// The Query

$args = array('post_type' => 'post',
              'category_name' => 'ABC',
              'tag' => 'XYZ',
              'meta_key' => 'priority',
              'orderby' => 'meta_value_num'
             );

$the_query = new WP_Query($args);

// The Loop
if ( $the_query->have_posts() ) {
    while ( $the_query->have_posts() ) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
} else {
    // no posts found
}
/* Restore original Post Data */
wp_reset_postdata();
?>

Something like this may solve your problem.

NOTE: I din't test this one, try yourself with it. If you face any problem, please comment here, or if you find any solution, don't forget to share that with me here.
